Product = changing the world for the better. Your money = an expression of value which you given. Wealth = freedom to be who you want, to live where you want, the going way you want. If you are not biulding own dream, then you are living for someone else's dream, living for someone else's well-being

You want wealth because it buys you freedom—so you don’t have to wear a tie like a collar around your neck; so you don’t have to wake up at 7:00 a.m. to rush to work and sit in commute traffic; so you don’t have to waste your life grinding productive hours away into a soulless job that doesn’t fulfill you.

The purpose of wealth is freedom; it’s nothing more than that. It’s not to buy fur coats, or to drive Ferraris, or to sail yachts, or to jet around the world in a Gulf Stream. That stuff gets really boring and stupid, really fast. It’s about being your own sovereign individual.

So what should one do? One should help people, and take care of the world. Those two are obvious. But is there anything else? When I ask that, the answer that pops up is Make good new things.

I can't prove that one should do this, any more than I can prove that one should help people or take care of the world. We're talking about first principles here. But I can explain why this principle makes sense. The most impressive thing humans can do is to think. It may be the most impressive thing that can be done. And the best kind of thinking, or more precisely the best proof that one has thought well, is to make good new things.

I would like to die with the thought that humanity has a bright future.
