I would consider...Google Plus a push technology. It's closer to Twitter than to Facebook.

Sales fixes everything.

Pursue joy, not happiness. This is probably the hardest lesson of all to learn. It probably seems to you that the goal in life is to be happy. Oh, you maybe have to sacrifice and study and work hard, but, by and large, happiness should be predictable.

Don't ask people to do something you wouldn't.

The hard part is implementing the decision, not making it.

My recommendation for SEO is very simple. It’s Write Good Stuff. In my mind, Google is in the business of finding good stuff. It has thousands of the smartest people in the world, spending billions of dollars to find the good stuff. All you have to do is write the good stuff; you don't need to trick it. Let Google do its job and you do your job.

The desire to change the world is a tremendous advantage as you travel down the difficult path ahead because focusing on a lofty goal is more energizing and attracts more talent than simply making a buck.
