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

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. 

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

If you fail, next time fail better.

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

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

99% of genius comes from hard work, the remaining 1% comes from innate talent

Go as far as you can see, when you get there, you’ll be able to see further

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

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

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