Poisonous people do not deserve your time. To think otherwise is masochistic.

It is predicated on the assumption that you dislike what you are doing during the most physically capable years of your life. This is a nonstarter—nothing can justify that sacrifice.

Excitement is the more practical synonym for happiness, and it is precisely what you should strive to chase. It is the cure-all.

I'm not averse to making a lot of money. But where does that end? I hang out with people with hundreds of millions of dollars. Is that the standard by which I should measure myself? Where does that take you if you're in my business? I think it takes you to pretty dark, corrupt places.

Age doesn't matter. An open mind does.

Alternating periods of activity and rest is necessary to survive, let alone thrive. Capacity, interest, and mental endurance all wax and wane. Plan accordingly.

I do not equate productivity to happiness. For most people, happiness in life is a massive amount of achievement plus a massive amount of appreciation. And you need both of those things.
