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

I think, therefore I am.

Failure to prepare = preparing to fail

Pure mathematics is in its way, the poetry of logical ideas.

The greatest enemy to human potential is your comfort zone

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

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

Hard work beats talent when talent doesn't work hard.

It doesn’t matter where you start, it matters how you end

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

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

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. 

We learn more from failure than we do from success.

Fall down seven times, stand up eight.

The greatest mistake we make is living in constant fear that we will make one.
