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

We learn more from failure than we do from success.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

If you fail, next time fail better.

There are no shortcuts to any place worth going.

Never underestimate the importance of small steps. small steps = big changes. 

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

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

Success is a journey, not a destination.

A book a day keeps the stupidity away.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

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

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

The greatest enemy to human potential is your comfort zone
