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. 

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

The journey of a thousand miles begins with one step.

Don't fear failure, fear being in the same exact same place next year as you are now.

The journey of a thousand miles begins with one step. 

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

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