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

The temptation to quit will be the greatest when you are about to succeed

Everything you want is on the other side of fear

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

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

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

I think, therefore I am.

There are no shortcuts to any place worth going.

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

There are no bad mistakes in maths, only discoveries.

The greatest enemy to human potential is your comfort zone

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

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

We learn more from failure than we do from success.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.
