+1 The sooner in your career (or life) you get used to failing and learning from it, the more potential (or happiness) you will have.

I put "failure" in quotes because it's only failure if you don't pause to learn. If you try and come up short but also learning something, then it's not failure, it's a learning experience.

So...ya can't learn (read: grow) if you don't try.
