Do what you have always done and you will always be what you have always been

There are no bad mistakes in maths, only discoveries.

It is never too late to become what you might have been

The temptation to quit will be the greatest when you are about to succeed

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

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

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

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

We all have two lives. The second begins when we realise we only have one. 

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

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

Patience is when you’re supposed to get mad, but you choose to understand

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

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

You cannot escape the responsibility of tomorrow by evading it today
