Telling others what you're doing

I read somewhere, might have been on lw, that telling what you're doing might decrease your chance of success, because it provides a way to get compliments without actually having achieved anything yet. I suppose this depends on how you do it, though.

Gollwitzer et al. (2009). When intentions go public: Does social reality widen the intention-behavior gap?

Abstract (emphasis mine):

Based on Lewinian goal theory in general and self-completion theory in particular, four experiments examined the implications of other people taking notice of one's identity-related behavioral intentions (e.g., the intention to read law periodicals regularly to reach the identity goal of becoming a lawyer). Identity-related behavioral intentions that had been noticed by other people were translated into action less intensively than those that had been ignored (Studies 1–3). This effect was evident in the field (persistent striving over 1 week's time; Study 1) and in the laboratory (jumping on opportunities to act; Studies 2 and 3), and it held among participants with strong but not weak commitment to the identity goal (Study 3). Study 4 showed, in addition, that when other people take notice of an individual's identity-related behavioral intention, this gives the individual a premature sense of possessing the aspired-to identity.
