Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

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

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

99% of failures come from people who have the habit of making excuses.

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

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. 

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

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

We learn more from failure than we do from success.

The greatest mistake we make is living in constant fear that we will make one.

If you fail, next time fail better.

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

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

Procrastination is the thief of time and the enemy of success.
