People often remark that I'm pretty lucky. Luck is only important in so far as getting the chance to sell yourself at the right moment. After that, you've got to have talent and know how to use it.

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

You never can tell whether bad luck may not, after all, turn out to be good luck.

I base my calculation on the expectation that luck will be against me.

I sometimes think we consider too much the good luck of the early bird and not enough the bad luck of the early worm.

All this shows how much luck there is in human affairs, and how little we should worry about anything except doing our best.
