If the potential damage is moderate or in any way reversible, don't give people the chance to say no. Most people are fast to stop you before you get started but hesitant to get in the way if you're moving. Get good at being a troublemaker and saying sorry when you really screw up. Timothy Ferriss

There's no difference between a pessimist who says, "Oh, it's hopeless, so don't bother doing anything," and an optimist who says, "Don't bother doing anything, it's going to turn out fine anyway." Either way, nothing happens. Yvon Chouinard

Get so busy doing something about your situation that you don't have time to worry. As you take action, your confidence, courage and sense of control will return and wipe away your fears. Brian Tracy
