From “Let Them” to “Let Me”: 6 Leadership Lessons from The Let Them Theory

By: Han Diep

Most of us have replayed a conversation, questioned someone’s decision or tried to predict a reaction before it happened. At work, that turns into over-explaining, people-pleasing or managing details that belong to someone else. A busy mind makes all of that feel productive, even while it pulls us away from our own priorities.

Mel Robbins’ The Let Them Theory draws a line between what belongs to other people and what remains ours. This blog pulls together six key takeaways from the book, each one an application of the same line: you can’t control other people’s choices, opinions or behaviour, but you can control how you respond. Each takeaway puts that same idea to work in a different setting, exploring how a response-focused approach can shape the way we manage our time, receive feedback, set boundaries, share responsibility and handle situations that still require action.

Three WIL resources add a leadership perspective throughout: 

• Penny Izlakar’s Taking Control of Time and Energy 

• WIL’s Lead Beyond Today podcast conversation Impostor Syndrome Uncovered: A Deep Dive with Dr. Valerie Young and

• Penny Izlakar’s Evolving Your Mindset—from Individual Contributor to People Leader

1. Put your Attention Where it Can Make a Difference

Even the strongest proposal may meet resistance. A carefully explained decision may still disappoint someone, and thoughtful guidance cannot complete another person’s learning. 

Our effort shapes the conditions; the final response belongs to them.

Penny Izlakar reaches a similar conclusion in Taking Control of Time and Energy. Earlier in her career, an open calendar and constant availability left her busy, drained and reactive. Time-blocking, no-meeting zones and regular reviews of what depleted her created room for deeper work and stronger decisions.

Our mental load deserves the same review. Replaying a meeting or rehearsing every possible outcome can crowd the mind as quickly as back-to-back appointments crowd a schedule. 

When we stop trying to manage someone else’s reaction, we can focus on what to do next.

Try this: Divide a page into “Mine” and “Not Mine.” Place your preparation, words and follow-through under “Mine.” Put other people’s moods, opinions and final decisions in the other column. Choose one action from your side.

2. Treat Opinions as Information, Not Instructions

Pressure to appear capable, agreeable and easy to work with can change how women show up. An idea gets softened before anyone hears it and a simple no grows into a long explanation. Preparation continues well beyond what the moment requires, and slowly, approval becomes the measure of whether the work was good enough.

WIL’s Lead Beyond Today conversation with Dr. Valerie Young offers another way forward. In Impostor Syndrome Uncovered, she explains how capable people can interpret uncertainty, mistakes or fear as proof that they do not belong. Her “Humble Realist” concept encourages us to respect what we know, acknowledge what we still need to learn and keep moving without demanding perfection.

Feedback deserves thought, but every comment carries a different weight. Consider who offered it, what evidence supports it and whether a pattern needs attention. 

Confidence grows when someone else’s opinion informs reflection without making the decision for us.

Try this: When feedback stings, pause. Separate what seems useful, what needs more context and what may simply reflect someone else’s preference.

3. Make your Boundaries Visible

A boundary clearly communicates our limits and what others can expect from us. It focuses on the choices we will make rather than telling someone else how to behave. Compare “you need to stop messaging me after hours” with “I review non-urgent messages during working hours.” The first tries to change someone else’s behaviour, the second explains what they can expect from you.

Penny’s method in Taking Control of Time and Energy shows how limits can become part of everyday routines rather than emergency measures. A focus block protects concentrated work, a no-meeting window keeps part of the day from disappearing, and a regular calendar review highlights what could be delegated, delayed or simplified. These small choices protect capacity before frustration builds. They also show colleagues and team members what thoughtful, sustainable work can look like.

Try this: Name the situation, state your limit and offer the next realistic option: “I want to give this proper attention. I cannot add it today, but I can review it Thursday.”

4. Give People Room to do Good Work

At work, the urge to manage every outcome often appears as micromanagement - rewriting a colleague’s draft, stepping into each decision or assuming a different method must be wrong. The intention may come from high standards, yet the result can be a team that waits for approval instead of building judgment.

Penny’s blog on Evolving Your Mindset—from Individual Contributor to People Leader explores this shift in detail. After building a career through strong individual work, stepping back can feel like contributing less. The article offers a better measure of leadership: are the people around us becoming more confident, capable and ready to make decisions?

Giving others room still requires clear outcomes, roles, deadlines and decision-making authority. Once those expectations are understood, a different style deserves the chance to succeed because strong work will not always look exactly like our own.

Try this: Before stepping in, ask whether the result faces a genuine risk or the idea merely feels unfamiliar. When the work remains on track, try: “walk me through your thinking.”

5. Pay attention to Patterns, Not Assumptions

Stepping back allows us to see more clearly how people follow through. One missed commitment may be an isolated situation, while a repeated pattern signals that a conversation may be needed. Focus on what happened rather than assuming why it happened. “The deadline was missed twice” describes the facts; “they don’t care” assigns a motive. Unclear expectations, competing priorities, accessibility needs or a skills gap could all be contributing factors.

Penny’s Evolving Your Mindset—from Individual Contributor to People Leader frames delegation as a development opportunity. A well-defined assignment paired with the right context and support can reveal strengths as well as areas that need coaching. Follow-through then provides useful information for deciding whether to offer more guidance, clarify accountability or extend greater responsibility. 

Try this: Start by stating the facts and asking what got in the way. From there, agree on a clear next step and follow up to see what changes.

6. Know When the Moment Still Calls for Action

We may not control how someone reacts, but we remain responsible for speaking up when action is needed. Discrimination, harassment, unsafe conditions, harmful behaviour and missed expectations should always be addressed clearly and directly.

Dr. Young’s “Humble Realist” concept offers useful guidance here. Perfect confidence rarely arrives before a difficult conversation. Careful preparation, openness to new information and a willingness to move through discomfort matter far more.

Penny’s Evolving Your Mindset—from Individual Contributor to People Leader adds an important layer of accountability. Giving people room to work still requires clear expectations and follow-through. When a commitment goes unmet, address the concern, listen to their perspective and agree on what needs to change. They may disagree with the decision or feel disappointed by a boundary, but their reaction belongs to them. Our responsibility lies in communicating respectfully and taking the appropriate next step.

Try this: Prepare three sentences, “the fact I need to address is…,” “the impact is…,” and “the next step I am asking for is...”

Final Thoughts: Make Room for What is Yours

Across all six takeaways, the same idea returns: we cannot decide how others think, act or respond, but we can choose what happens next. That choice will look different depending on the moment. It may mean protecting focused work, considering feedback without losing self-trust, giving colleagues space to solve problems or speaking up despite uncertainty.

Robbins captures this balance through two phrases. “Let Them” helps us release what belongs to others, while “Let Me” directs our attention back to our own choices. When someone else’s behaviour begins consuming your attention, pause and ask: what belongs to them, and what is mine to do next?
