With all respect to Derek, I suspect this advice depends on personality type. For me, common wisdom is 100% correct.
A goal no one knows about is easy to quit without loss of face. But if all my friends know I'm doing something, I'm bloody well going to do it.
I always tell my friends I'm going to do something when it's something that really needs to get done. So far, whatever dopamine reward I get from talking about it has overpowered by the knowledge that I said I'd do it and it's not done yet.

As always, your experience may vary.
