Conventional wisdom says that making your goals public motivates you to achieve them. Not so, says Derek Sivers:

Tests done since 1933 show that people who talk about their intentions are less likely to make them happen.

Announcing your plans to others satisfies your self-identity just enough that you’re less motivated to do the hard work needed.

I think he’s right. You get a kind of vicarious thrill from announcing grand, impressive goals to the world. You get a temporary rush of pride and self-confidence, which doesn’t carry over into actual drive to work.

That’s pretty much the hole I dug myself into last year.
