Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

You cannot start the next chapter of your life if you keep re-reading the last one.

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

We learn more from failure than we do from success.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

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

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

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

The power of reflection is the most powerful skill you’ll learn.

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

Tomorrow is worth more than yesterday but less than today.

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

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