Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

We all make mistakes. What matters is how we choose to move forwards from them.

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. 

A hero is no braver than an ordinary man, but he is braver five minutes longer.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

No one starts out on top. You have to work your way up.

Time is your friend, impulse is your enemy.

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

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

You can have results or excuses, not both

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

You cannot escape the responsibility of tomorrow by evading it today

If you fail, next time fail better.

I have not failed, I've just found 10,000 ways that won't work.
