Tough times never last, but tough people do.

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

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. 

Procrastination is the thief of time and the enemy of success.

I think, therefore I am.

Don’t be afraid to work hard and find out how good you can really be.

The greatest enemy to human potential is your comfort zone

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Fall down seven times, stand up eight.

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

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

It always seems impossible until it's done.

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