I don't agree with everything on Scott Sternberg's rules of style list, but a couple of his points are pretty interesting. I'll spot you this one:
Whenever you start a new project or a new job, don't tell anyone what you're working on, because it can change direction a million times and once you start telling the world about it, you get constrained by your own mouth.
but you'll have to find the others on your own. (via andrea inspired)
Update: A recent study has indicated that people who don't share their goals are more successful in achieving them.
Researchers report that when dealing with identity goals -- that is, the aspirations that define who we are -- sharing our intentions doesn't necessarily motivate achievement. On the contrary, a series of experiments shows that when others take notice of our plans, performance is compromised because we gain "a premature sense of completeness" about the goal.
