No matter what you do, there is always someone bigger, faster, and better then you. There is no stopping it. The only thing we can do is give it everything we have and hope to come out on the other side a little bit better.
I beleive if we attack our work with an overwhelming passion and percistance, there is no way to fail. Ignoring passion and percistance is not an easy thing to do.
So make it tough to ignore you. Do what you love. And don't let the bigger guy stop you.
