Paraphrasing words of wisdom from my dharma friend Tom:

There would be a bump on the wheel whether you went fast or slow or no matter where you went. You just have to know that bump is coming up and continue on the journey.

If someone handed you a mic and said get up there on stage and sing would you sit there and worry about being electrocuted? In the next second, a MAC truck could drive through the building and drive over your chair and the safest place for you would have been the stage. So are you going to get crushed without doing what you really want to do?
