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

The road to success is like a staircase. If you want to succeed, double your failure rate

Dreams don't work unless you do.

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

We learn more from failure than we do from success.

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

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

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

Don’t be afraid to work hard and find out how good you can really be.

Mistakes have the power to turn you into something better than you were before.

The bad news is time flies, the good new is that you're the pilot.

You cannot escape the responsibility of tomorrow by evading it today

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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. 

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