Our destiny exercises its influence over us even when, as yet, we have not learned its nature: it is our future that lays down the law to our to-day.

One must never ask of fortune more than she can grant.

We all know you don't get successful just by having a good idea or working hard. You get successful by being lucky too. If I had to support my family growing up, instead of having the time to learn how to code. If I didn't know that I was gonna be fine if Facebook didn't work out, then I wouldn't be standing up here today. And if we're honest, we all know how much luck we've had.

I don't believe in leaving things to luck. I believe in hard work and preparation.

Luck and destiny are the excuses of the world's failures.

Death and life have their determined appointments; riches and honors depend upon heaven.
