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

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

Try and do one thing each day that you would really rather not do.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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

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

Failure to prepare = preparing to fail

Fall down seven times, stand up eight.

Shoot for the moon and even if you miss you’ll land among the stars/

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. 

Failure is NOT your destiny. Failure is the key to success.

No one starts out on top. You have to work your way up.

Don’t hang your targets after you’re done shooting.

Procrastination makes easy things hard and hard things harder.
