Everything that happens was once a dream.

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

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

A book a day keeps the stupidity away.

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

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

We learn more from failure than we do from success.

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

Fall down seven times, stand up eight.

It is never too late to become what you might have been

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

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

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

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. 

If you can understand just one thing thoroughly, then you will understand everything.
