Instead of finding reasons why you can't, find reasons why you can.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

We learn more from failure than we do from success.

There are no bad mistakes in maths, only discoveries.

The road to success is like a staircase. If you want to succeed, double your failure rate

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

We all have two lives. The second begins when we realise we only have one. 

Failure to prepare = preparing to fail

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

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

I think, therefore I am.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

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

We learn more from failure than we do from success.

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