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.

Failure is not the opposite of success, it is part of the success.

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

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

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

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

Skills are built not born.

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

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

Don’t practice until you get it right, practice until you can’t get it wrong.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

Failure to prepare = preparing to fail

Life is full of opportunities. With every opportunity that is missed, another one is born.

Your attitude is everything. Pick a good one.
