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

Skills are built not born.

If you fail, next time fail better.

Your limitation - its only your imagination.

In order to become better than anybody else you must first become better than yourself.

It is never too late to turn an unproductive day into a productive one.

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

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

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

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

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

Dreams don't work unless you do.

The road to success is like a staircase. If you want to succeed, double your failure rate

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

There is no elevator to success, you have to take the stairs.
