Instead of finding reasons why you can't, find reasons why you can.

I think, therefore I am.

There are no bad mistakes in maths, only discoveries.

The journey of a thousand miles begins with one step. 

Success is not final and failure is not fatal. It is the courage to continue that counts.

Failure is NOT your destiny. Failure is the key to success.

Hard work - a two way street where you get exactly what you put in.

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

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.

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

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

Success can never happen without the journey (struggle).

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

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

Try and do one thing each day that you would really rather not do.
