If you have the opportunity to go be an early employee at a company that's just going crazy, and you believe it's the next Facebook or Google, you should go join that company.

For most of the early hires you make in a startup, experience doesn't matter very much, and you should go for aptitude.

Set a clear, easy-to-understand vision for your company, and make it be a mission people believe in.

I believe in the future, and to be a good investor, you have to believe in the future.

Being a public company is really terrible for most companies. I'd say Facebook and Google have done a pretty good job of standing up to the incredible quarterly pressure to hit numbers, but most companies - and I've observed a lot now - don't do a very good job of that.

I don't believe that employers should have access to an employee's private passwords, including Facebook.
