Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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

Just stick with it, what seems hard now will one day be your warm up.

There is no elevator to success, you have to take the stairs.

Go as far as you can see, when you get there, you’ll be able to see further

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

Procrastination makes easy things hard and hard things harder.

Shoot for the moon and even if you miss you’ll land among the stars/

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Dreams don't work unless you do.

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

You can have results or excuses, not both

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

If you fail, next time fail better.
