Your attitude is everything. Pick a good one.

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

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

Mistakes have the power to turn you into something better than you were before.

Success can never happen without the journey (struggle).

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

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

The road to success is like a staircase. If you want to succeed, double your failure rate

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

Failure to prepare = preparing to fail

You can hire a tutor but you can't hire someone to practice for you.

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

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

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

Success is a journey, not a destination.
