Nothing is impossible if you want it badly enough. Impossible = I'm possible.

There is no elevator to success, you have to take the stairs.

Fall down seven times, stand up eight.

I think, therefore I am.

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. 

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

99% of failures come from people who have the habit of making excuses.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

There are no shortcuts to any place worth going.

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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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

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

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