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

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

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

Your attitude is everything. Pick a good one.

If you want to succeed, double your failure rate.

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

Everything that happens was once a dream.

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.

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

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Success can never happen without the journey (struggle).

You can have results or excuses, not both

The journey of a thousand miles begins with one step. 

Failure to prepare = preparing to fail
