It's not easy to break out of your comfort zone. People will tear you down, tell you you shouldn't have bothered in the first place. But let me tell you something: there's not much of a difference between a stadium full of cheering fans and an angry crowd screaming abuse at you. They're both just making a lot of noise. How you take it is up to you. Convince yourself they're cheering for you. You do that, and someday, they will.
