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

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. 

It always seems impossible until it's done.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

The temptation to quit will be the greatest when you are about to succeed

Don’t practice until you get it right, practice until you can’t get it wrong.

A book a day keeps the stupidity away.

We all have two lives. The second begins when we realise we only have one. 

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

You cannot start the next chapter of your life if you keep re-reading the last one.

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

Hard work beats talent when talent doesn't work hard.

In order to become better than anybody else you must first become better than yourself.

Patience is when you’re supposed to get mad, but you choose to understand

Everything that happens was once a dream.
