I think, therefore I am.

The bad news is time flies, the good new is that you're the pilot.

We learn more from failure than we do from success.

Start, struggle, fail, fix and learn. Repeat.

Tough times never last, but tough people do.

If you fail, next time fail better.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

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

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. 

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

Procrastination makes easy things hard and hard things harder.

Time is your friend, impulse is your enemy.

The journey of a thousand miles begins with one step.
