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

Failure is not the opposite of success, it is part of the success.

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

Everything that happens was once a dream.

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

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

If you want to succeed, double your failure rate.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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

It is never too late to turn an unproductive day into a productive one.

There are no shortcuts to any place worth going.

Don't fear failure, fear being in the same exact same place next year as you are now.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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

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.
