failure is an inevitable part of the game

Start the process of tinkering. Don't put your hand on a hot burner (please), but do start a new web site, a new marketing campaign, or a new Web community. Why? The answer, you will quickly come to realize, is that, with everything you decide to do, "it's so crazy that it just might work." Understand that failure is an inevitable part of the game, but that the chance of success is much greater the more often you roll the dice. You shouldn't fear it; you should embrace it.
