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

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

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. 

Fall down seven times, stand up eight.

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

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

Time is your friend, impulse is your enemy.

Skills are built not born.

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

Try and do one thing each day that you would really rather not do.

Everything that happens was once a dream.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

Pure mathematics is in its way, the poetry of logical ideas.

Success is a journey, not a destination.
