Start, struggle, fail, fix and learn. Repeat.

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.

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

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

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

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

You can hire a tutor but you can't hire someone to practice for you.
