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

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

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. 

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.

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.

We learn more from failure than we do from success.

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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

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

Run in the morning before your body figures out what you're doing

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

The journey of a thousand miles begins with one step.
