Fall down seven times, stand up eight.

Tough times never last, but tough people do.

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.

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

There are no bad mistakes in maths, only discoveries.

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. 

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

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

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

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

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

Success is the sum of small repeated efforts, day in and day out.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

You cannot start the next chapter of your life if you keep re-reading the last one.
