Just stick with it, what seems hard now will one day be your warm up.

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

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

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

Procrastination is the thief of time and the enemy of success.

Practice like you’ve never won. Perform like you’ve never lost.

You can have results or excuses, not both

Do what you have always done and you will always be what you have always been

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.

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

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

You're not in competition with anyone but yourself. Outdo your past, not other people.

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

Your limitation - its only your imagination.
