We all have two lives. The second begins when we realise we only have one. 

The temptation to quit will be the greatest when you are about to succeed

It always seems impossible until it's done.

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

Run in the morning before your body figures out what you're doing

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

The wise person knows that no answer is also an answer

If you fail, next time fail better.
