Believe it or not, I don't have personal experience with everything. Failure is no exception. Having had my fair share of failures, I will say I don't have a notable amount of experience with it. But what I have learned, from both my own failures and seeing others, is that there are two main reasons for failure to happen. The first is simply because it's a fact of life. We're human. One can't accomplish everything.
The second reason one can fail is the one I want to focus on. The second reason one can fail is because there's a better door elsewhere. One can come up short not because one's not good enough, but because there is something so much better in store.
So take heart, my friends. The only way you can fail is to excel. So what is it you would try . . .

. . . if you can't fail?
