No one achieves greatness by becoming a generalist. You don't hone a skill by diluting your attention to its development. The only way to get to the next level is focus.

The experience of pain or loss can be a formidably motivating force.
To do something really big, let go of your ego, and get ready to be part of a team.
Experience teaches nothing, but evaluated experience teaches everything.
Failure should be our teacher, not our undertaker
