If you have a really good idea, stick to it, but be flexible on how you get there. Be stubborn on your vision but flexible on the details... People who are right a lot change their mind... They have the same data set that they had at the beginning, but they wake up, and they re-analyze things all the time, and they come to a new conclusion, and then they change their mind.

If everything you do needs to work on a three-year horizon, you’re competing against a lot of people.

But if you’re willing to invest on a seven-year horizon, you’re now competing against a fraction of those people, because few companies are willing to do that.
