We all have a deep need to feel in control, which is why we try to shape the people and situations around us to fit our expectations and preferences. But this is an exercise in futility that only makes us frustrated and anxious and sets us up for conflict with the people in our lives. In The Let Them Theory (2024), Mel Robbins contends that we need to shift our mindsets so we can stop wasting energy trying to control other people’s thoughts, feelings, and actions. She writes that the best way to keep other people from sapping your energy is to “Let Them” be who they are, while focusing on what you can control: yourself and your own responses.

Robbins explains that this simple shift frees you from the draining cycle of trying to manage what other people think and do....

The Let Them Theory Summary What Is the Let Them Theory?

Robbins’s Let Them Theory teaches us to detach from situations and behaviors that are outside our sphere of influence. It involves shifting your mindset to take control of what you do and how you spend your time and energy. She explains that we have a natural need to feel like we’re in control because we fear that things will go wrong if we aren’t in control—and we think that if we can just influence those around us, we’ll find a way to make our lives better and avert potential problems. But we can’t control other people’s actions or opinions, and trying to do so just makes us more stressed, anxious, miserable, and drained. It saps our energy, robs us of our peace of mind, and distracts us from creating the lives we want.

How We’re Wired to Seek Control

Neuroscience research suggests our desire for control is biologically hardwired, not just culturally learned. Researchers have found that believing we can control our environment (and attempting to) is not merely preferable: It’s a psychological and biological imperative for survival. Our brain's reward system reinforces this drive for control. When we make...

The Let Them Theory Summary Why Do “Let Them” and “Let Me” Work?

Robbins points out that our time and energy are precious resources that we need to invest wisely. When we allow external factors to drain us emotionally and mentally, we deplete the reserves we need to work toward our goals, deepen our relationships, and improve our well-being. Stress and negative emotions are a natural consequence of letting other people deplete our time and energy, and these can have detrimental effects on our physical and mental health, with results like burnout, anxiety, and depression. Robbins contends that if you protect your energy with the Let Them Theory, you can carve out the space for a more positive, productive, and fulfilling life.

She also explains that when you stop trying to influence what other people say and do, you not only regain precious time and energy, but you learn to protect your emotional well-being, too. When you let go of the need to control others, you free yourself from the frustration and emotional upheaval that comes with trying to manage situations beyond your influence. This newfound peace of mind allows you to approach life with greater clarity and intention—and to better see situations and relationships for what they...

The Let Them Theory Summary How Can You Use the Let Them Theory?

Robbins contends that the Let Them Theory can be applied to all areas of your life, from work to friendships to romantic relationships. At its core, conserving your energy and protecting your peace with the Let Them Theory is a two-step process:

1. Recognize and acknowledge situations or behaviors that are outside your control. In these moments, when you notice you’re reacting negatively to someone’s choices, consciously say “Let Them” to yourself, signaling your detachment from judging them and letting go of your need to change, control, or criticize them.

2. Shift your focus to what you can control: your thoughts, actions, and responses. Reflect on how you want to think, act, and speak, and how you can align your next steps with your core values. Say “Let Me” and take a deep breath, resetting your body’s stress response, and reclaim your responsibility to act positively.

Sailing Against the Wind

The Let Them Theory has a parallel in sailing, an activity where success depends entirely on working with forces you cannot control. Sailors understand a fundamental truth: You cannot sail directly against the wind. Attempting to do so leaves you stalled and...

The Let Them Theory Summary Take Control of Your Relationships

Saying “Let Them” and “Let Me” gives you a way to take responsibility for your relationships. Other people’s words and actions can send us on an emotional rollercoaster: When we internalize the negative things they say and do, we often feel inferior. For example, if your colleague walks into the office one morning and immediately snaps at you, you’d likely feel you must have done something wrong that justifies their rudeness. But they might just be in a bad mood because their shoelace broke or they missed their train—circumstances that don’t involve you.

Conversely, as we discussed earlier, it can make you feel superior to just think “let them” and dismiss your colleague’s behavior—thinking you’re the bigger person who’s above such pettiness or judging them for being rude. But that wouldn’t be a productive way forward, as it still involves judgment rather than true acceptance.

Robbins explains that you’re responsible for building the relationships you want with other people. In the situation with your grumpy colleague, that means that you wouldn’t respond to their rudeness in kind, but instead look at them with empathy and figure out how you can make their day better....

The Let Them Theory Summary Stop Being Stressed Out by Other People’s Opinions

The Let Them Theory also works when it’s what other people think and say—rather than what they do—that stresses you out. Inevitably, people will have and express negative opinions about you. But if you let their opinions influence your decisions, then you give up control over what you do with your life. Robbins points out that just as we can’t change what thoughts pop into our own heads, it’s impossible to control what other people think. She recommends expecting that other people will think negative thoughts about you—and resolving to follow your own path anyway. Instead of letting your fear of other people’s negative opinions constrain you, you can make decisions you’re proud of and live according to your own values.

(Shortform note: Robbins’s advice to avoid stress over others’ opinions aligns with research on how malleable human opinions actually are. Studies reveal that people’s opinions change far more often than they realize: Thanks to the protection of our “psychological immune system,” we unconsciously adjust our opinions to make peace with circumstances we can’t change....

The Let Them Theory Summary Let Go of Your Fear of Other People’s Emotional Reactions

In the same way that managing other people’s negative opinions isn’t your responsibility, it’s also not your responsibility to manage other people’s emotional reactions. When you make decisions to avoid disappointing someone, to keep someone from getting angry at you, or because you know they’ll make you feel guilty if you don’t, you’re letting other people’s emotions dictate your decisions. Robbins explains that it’s hard but necessary to set boundaries and “Let Them” react. In doing so, you give people space to feel their emotions, and you release yourself from feeling like you have to manage or fix those emotions for them.

She explains that most people have the emotional maturity of an eight-year-old: They’ve never learned to process their emotions and communicate their needs in a healthy way because many parents inadvertently teach their children to suppress their emotions instead of finding a healthy way to express them. But Robbins explains that when an adult wants to act like an eight-year-old, you should just “Let Them.” Then, when you remind yourself to “Let Me” decide how to respond, you realize that their emotions aren’t yours to manage and it’s up to you to...

The Let Them Theory Summary Stop Pressuring Other People to Change

If you’ve ever tried to push somebody else to change, then you know it almost never works. Instead, you have to create an environment of acceptance and love to enable people to make changes in their own time. We all have a fundamental need for autonomy and control over our lives, and we naturally resist attempts by others to force change because these attempts threaten this core need. However, when we feel fully accepted and loved unconditionally, we’re free to look inward and find our own motivation to grow.

Robbins recommends several steps to create this supportive environment: Practice radical acceptance of others without judgment, express unconditional love while separating who they are from behaviors you dislike, be patient as change happens naturally, celebrate positive steps, and provide resources only when asked. By modeling the positive changes you’d like to see rather than criticizing or controlling, you allow them space to decide for themselves that they want to change. The goal isn’t to enable self-destructive behavior but to provide the emotional safety that makes meaningful change possible. Paradoxically, when people feel truly accepted as they are, they...

The Let Them Theory Summary Build a Healthier Relationship With Yourself

Finally, Robbins explains that you can use the Let Them Theory to improve the relationship you have with yourself. She notes that you are the only person that you’re guaranteed to spend the rest of your life with, and you owe it to yourself to make your happiness and dreams a priority. When you let other people do what they want to do (and resolve to not allow them to determine what you do), you decide to build the life you want without worrying about other people’s approval or validation. Robbins notes you can use “Let Them” and “Let Me” to give yourself the power to become your own source of happiness, to define what’s important to you, and to take control of how you work to turn your reality into the life you want.

Shortform Exercise: Put “Let Them” and “Let Me” in Action

Robbins’s method has two components: “Let Them,” which lets you detach yourself from others’ behaviors, opinions, and emotional reactions, and “Let Me,” which means taking responsibility for your own thoughts, feelings, and actions. In this exercise, you’ll apply these two principles to a real-life situation.

Briefly describe a specific situation where you’re trying to control or change someone else’s behavior. This could be a coworker’s negativity, a family member’s criticism, a romantic partner’s inconsistency, or a friend’s reliability issues.
