From one of my favorites, Seth Godin.

Make something happen

“If I had to pick one piece of marketing advice to give you, that would be it.

Now.

Make something happen today, before you go home, before the end of the week. Launch that idea, post that post, run that ad, call that customer. Go the edge, that edge you’ve been holding back from… and do it today. Without waiting for the committee or your boss or the market. Just go.”
