We learn more from failure than we do from success.

Do what you have always done and you will always be what you have always been

Don’t be afraid to work hard and find out how good you can really be.

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

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.

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

The journey of a thousand miles begins with one step. 

Your attitude is everything. Pick a good one.

I think, therefore I am.

You can have results or excuses, not both

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

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

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

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

Knowledge is of no value unless you put it into practice.
