Whenever you find yourself doubting how far you can go, just remember how far you have come.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

Success can never happen without the journey (struggle).

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

If you fail, next time fail better.

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

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

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

I have not failed, I've just found 10,000 ways that won't work.

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

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

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

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