There is great wisdom in being able to realise that you don’t understand something before it goes too far.

Don’t practice until you get it right, practice until you can’t get it wrong.

Everything that happens was once a dream.

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

A book a day keeps the stupidity away.

The wise person knows that no answer is also an answer

Don’t hang your targets after you’re done shooting.

Do what you have always done and you will always be what you have always been

If you can understand just one thing thoroughly, then you will understand everything.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

You cannot escape the responsibility of tomorrow by evading it today

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

If you want to succeed, double your failure rate.

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

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