Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

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

Failure to prepare = preparing to fail

If you fail, next time fail better.

You're not in competition with anyone but yourself. Outdo your past, not other people.

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

The bad news is time flies, the good new is that you're the pilot.

He who has begun his task is half-way done. Have the courage to begin!

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

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

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

Don’t hang your targets after you’re done shooting.

Never underestimate the importance of small steps. small steps = big changes.
