An MBA is a great degree for career paths like investment banking, finance, consulting, and large companies. An MBA is not necessarily the right path for starting a tech company. You should be building a prototype, not getting an MBA in that case.

Try stuff. I also used to believe that it's better to be smart than lucky because if you're smart you can out-think the competition. I don't believe that anymore-this is not to say that you should strive for a high level of stupidity. My point is that luck is a big part of many successes, so (a) don't get too bummed out when you see a bozo succeed; and (b) luck favors the people who try stuff, not simply think and analyze. As the Chinese say, "One must wait for a long time with your mouth open before a Peking duck flies in your mouth."

Simple and to the point is always the best way to get your point across.

You know you're ready to write a book when you have a feeling that you should do it, no matter what anybody says. It's like falling in love or starting a company. When you're still wondering if you should get married or you're still wondering whether you should start a company that might be not the right person or the right idea. And writing is the same way. When you've locked on to the topic, you'll just write it.

If you're an entrepreneur and you think that the president makes a difference to your business, you should stay at your current job.

There is only one Steve Jobs, but if you want a shot at being the next Steve Jobs, learn to communicate using stories, demos, and pictures.

Remember that nobodies are the new somebodies.
