There are no bad mistakes in maths, only discoveries.

Life is full of opportunities. With every opportunity that is missed, another one is born.

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

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

Your attitude is everything. Pick a good one.

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

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.

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

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

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

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Tough times never last, but tough people do.

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

You can have results or excuses, not both

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.
