Mark Cuban's speech at Blog World Expo contained several funny anecdotes, but my favorite was his story about one of his first business ventures. He sold powdered milk. As Mark explained it, he thought it tasted as good as regular milk, you could store it longer, it just seemed to have a lot of benefits. He even sold some… to his parents.
I dug through Mark's blog archives and found an old post referencing the story. It's an excellent post over all about the need for just one success in business, and why it is worth it to keep trying.
In basketball you have to shoot 50pct. If you make an extra 10 shots per hundred, you are an All-Star. In baseball you have to get a hit 30 pct of the time. If you get an extra 10 hits per hundred at bats, you are on the cover of every magazine, lead off every SportsCenter and make the Hall of Fame.
In Business, the odds are a little different. You don't have to break the Mendoza line (hitting .200). In fact, it doesnt matter how many times you strike out. In business, to be a success, you only have to be right once.
One single solitary time and you are set for life. That's the beauty of the business world.
The post is a great motivational story, so go read the whole thing.
