These words come from comedian Bill Cosby. They serve to remind us that we're not willing to truly take important risks until our desire for what we want surpasses the fear of potential failure.
We tend to restrict ourselves because of the unknown, often worrying about all the bad things that could happen if we take a risk and fall flat on our faces. It's hard to go after something we want when we're constantly worried about failure. If you don't want it bad enough, the fear will always come first. You have to decide that you want it more.
