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

Mistakes have the power to turn you into something better than you were before.

There are no shortcuts to any place worth going.

The journey of a thousand miles begins with one step.

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. 

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.

Failure to prepare = preparing to fail

99% of genius comes from hard work, the remaining 1% comes from innate talent

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

Success is a journey, not a destination.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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

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

Tough times never last, but tough people do.

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