A failure is like fertilizer; it stinks to be sure, but it makes things grow faster in the future.
Stop stewing and start doing!
You must be worthy of the best, but not more worthy than the rest.
All of the top achievers I know are life-long learners. Looking for new skills, insights, and ideas. If they're not learning, they're not growing and not moving toward excellence.
Instead of just letting life happen, I'm going to make it happen for me.
Stop rationalizing, stop stewing. Get up out of your chair and start doing.
