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

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

You're not in competition with anyone but yourself. Outdo your past, not other people.

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

You can have results or excuses, not both

Your attitude is everything. Pick a good one.

You cannot escape the responsibility of tomorrow by evading it today

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

Your limitation - its only your imagination.

The master has failed more times than the beginner has even tried

Patience is when you’re supposed to get mad, but you choose to understand

We learn more from failure than we do from success.

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

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.
