Unfortunately the mind sometimes has a nasty habit of sabotaging our best attempts to control ourselves. Recent research by Gollwitzer et al. (2010) suggests that, in fact, making our goals public can have precisely the opposite effect from what we intend.

Seems the best way to approach your goals is to just do them.
