Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

There are no shortcuts to any place worth going.

You're not in competition with anyone but yourself. Outdo your past, not other people.

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

If you fail, next time fail better.

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

We all have two lives. The second begins when we realise we only have one. 

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

It always seems impossible until it's done.

Your attitude is everything. Pick a good one.

Practice like you’ve never won. Perform like you’ve never lost.

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

It is never too late to become what you might have been

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

I think, therefore I am.
