Stop Trying to Fix People: Mel Robbins on the Power of Letting Go

Mel Robbins opens with a blunt observation that frames the entire conversation: “The people that you love will not change on your timeline. They will not heal when you’re ready for them to heal. They will not get sober when you’re ready for them to get sober. People only change when they are ready to do the very difficult work to change for themselves.” The episode explores why trying to fix, push, or control others backfires, and what to do instead.

Why pushing people to change makes them resist

Robbins explains that the instinct to intervene when someone we love is struggling comes from a genuine place of caring—but the strategy is driven by our own stress and a hidden belief that the other person isn’t capable without us. That belief is the mistake. When we march in with advice, reminders, or criticism, we trigger the other person’s need to maintain control over their own life. They end up pouring energy into resisting our push rather than into the change itself. As Robbins puts it, “One of the biggest reasons why people don’t change is because they’re pouring so much energy into resisting your push to change. It’s how they stay in control of themselves—because if my husband all of a sudden starts exercising, now he has to admit that I’m right and he loses control of himself.”
