The journey of a thousand miles begins with one step. 

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

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.

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

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