You can have results or excuses, not both

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

The easiest person to deceive is yourself.

Your limitation - its only your imagination.

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

Success can never happen without the journey (struggle).

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

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. 

There are no shortcuts to any place worth going.

Mistakes have the power to turn you into something better than you were before.

Success is not final and failure is not fatal. It is the courage to continue that counts.

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

Practice like you’ve never won. Perform like you’ve never lost.

In order to become better than anybody else you must first become better than yourself.

There are no bad mistakes in maths, only discoveries.
