I think the best thing you can do is to be grateful for what you have.

每一个发现都建立在前人的工作之上。

We don't inherit the earth from our ancestors; we borrow it from our children—this must guide every business decision.

Friends have all things in common.

You have to be willing to take risks.

The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

I don’t let negativity affect me.
