My message to students is that if you want to become an entrepreneur and save the world, definitely don't skip college. But go to a school that you can afford. You'll be freed from the chains of debt and succeed on your own ambition and merit.

An open-minded and diverse population that readily shares information, encourages experimentation, accepts failure and dispenses with formality and hierarchy is what makes Silicon Valley the successful hub that it is.

Despite what some investors say, older age is an advantage in the startup world. You know more about industries and markets, and have ideas for products that the world actually needs and a better ability to motivate and manage than a kid out of school does.

Entrepreneurship is like a computer game in which you have to master every level before achieving success. Startups repeatedly stumble and have to go back to the drawing board. The best way to skip some levels and to increase the odds of survival is to learn from others who have already played the game.
