Mark Cuban: To me, the proof is always in the details. No matter what business Im in, most people work in headlines mode. They think that if they say or write something that makes a good headline , then there must be substance to their point. That’s not the way business works. Which is why most people never get further than the middle.

Substance comes from detail. Luck comes from detail. Winning comes from being willing to do the work on the details. Learning comes from investing in details.
