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

Time is your friend, impulse is your enemy.

Procrastination is the thief of time and the enemy of success.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

You cannot escape the responsibility of tomorrow by evading it today

It is never too late to turn an unproductive day into a productive one.

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

Don't fear failure, fear being in the same exact same place next year as you are now.

We learn more from failure than we do from success.

The journey of a thousand miles begins with one step.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Failure to prepare = preparing to fail

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

It always seems impossible until it's done.

In order to become better than anybody else you must first become better than yourself.
