The master has failed more times than the beginner has even tried

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. 

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

There are no bad mistakes in maths, only discoveries.

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

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

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

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

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 hang your targets after you’re done shooting.

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

We learn more from failure than we do from success.

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

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