A lot of people treat choosing their cofounder with even less importance than they put on hiring. Don't do this.

There's at least a hundred times more people with great ideas than people that are willing to put in the effort to execute them well.

The tenth social network, and limited only to college students with no money, also terrible. Myspace had won.

If you're not in college and you don't know a cofounder, the next best thing I think is to go work at an interesting company.

Move fast. Speed is one of your main advantages over large companies.

If you can just learn to think about the market first, you will have a big leg up on most people starting startups.

The best ideas often look terrible at the beginning the truly good ideas, don't seem like they're worth stealing.
