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

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

I think, therefore I am.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

It doesn’t matter where you start, it matters how you end

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

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

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.

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

You cannot escape the responsibility of tomorrow by evading it today

We learn more from failure than we do from success.

Knowledge is of no value unless you put it into practice.

No one starts out on top. You have to work your way up.

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