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/

It is never too late to become what you might have been

Failure is NOT your destiny. Failure is the key to success.

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. 

If you fail, next time fail better.

Just stick with it, what seems hard now will one day be your warm up.

Procrastination makes easy things hard and hard things harder.

The power of reflection is the most powerful skill you’ll learn.

Success can never happen without the journey (struggle).

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

Nobody said it’d be easy, they just promised it would be worth it.

We learn more from failure than we do from success.

If you can understand just one thing thoroughly, then you will understand everything.

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