Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

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.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

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

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

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.

I think, therefore I am.

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

If you can understand just one thing thoroughly, then you will understand everything.
