5 Reasons Quitting Feels So Hard (Even When You Know You Should)

We romanticize starting—new jobs, new projects, new goals. But quitting? That’s a different story. Walking away is often painted as failure when, in reality, it’s one of the hardest and healthiest decisions we can make. So why does it feel so awful to let go of something that’s clearly not working? Here’s the psychology behind why quitting messes with your mind—and why doing it anyway might be your smartest move yet.

1. We Hate Wasting Effort

Psychologists call it the sunk cost fallacy—the idea that the more time, money, or energy we’ve invested in something, the harder it is to abandon it. Even when staying costs us more. You’re not holding on because it’s right—you’re holding on because it once was. Quitting doesn’t erase your effort; it honors it by refusing to waste more.

2. Identity Gets Tangled Up in It

When you’ve built a career, relationship, or routine around something, quitting can feel like erasing part of who you are. But identity isn’t static—it’s editable. Sometimes walking away isn’t losing yourself; it’s updating yourself. Letting go isn’t failure—it’s evolution in real time.

3. Our Brains Crave Completion

We’re wired to finish things. The Zeigarnik effect—a psychological phenomenon—explains why unfinished tasks linger in our minds, nagging us until they’re complete. Quitting breaks that loop, which is why it feels uncomfortable. But completion doesn’t always mean continuing; sometimes it means choosing closure.
