Excerpt from Tools Of Titans, Tim Ferriss:
Noah Kagan on what would you put on a billboard?
"'It’s not about ideas, it’s about making ideas happen.' I'd put it on every college campus in the world. In our youth, we are wonderfully creative and idealistic... Truth is, young creative minds don't need more ideas, they need to take more responsibility with the ideas they've already got."
Similarly, think of all the meetings you are in where everyone gets a say. Everyone has a new idea, yet not many of them are executing any results or taking ownership of the ideas they throw out. Just like a pact between friends to always do sober what you said you would do whilst drunk, if someone has an idea then give them an action to execute that idea.
