Time is your friend, impulse is your enemy.

We learn more from failure than we do from success.

I have not failed, I've just found 10,000 ways that won't work.

The easiest person to deceive is yourself.

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

Success is not final and failure is not fatal. It is the courage to continue that counts.

Lose an hour in the morning and you will spend all day looking for it.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

Fall down seven times, stand up eight.

Tough times never last, but tough people do.

Pure mathematics is in its way, the poetry of logical ideas.

No one starts out on top. You have to work your way up.

Skills are built not born.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

You cannot start the next chapter of your life if you keep re-reading the last one.
