The market is not always right, but it is always there.
市场并不总是正确的，但它总是在那里。
If you're not stubborn, you'll give up on experiments too soon. And if you're not flexible, you'll pound your head against the wall and you won't see a different solution to a problem you're trying to solve.
I'm not a master, I'm a slave.
You were given this life because you are strong enough to live it.
