Failure is not the opposite of success, it is part of the success.

You cannot escape the responsibility of tomorrow by evading it today

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

The journey of a thousand miles begins with one step. 

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

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

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

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

Procrastination makes easy things hard and hard things harder.

Practice like you’ve never won. Perform like you’ve never lost.

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

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

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

Success can never happen without the journey (struggle).
