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

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

Skills are built not born.

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

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

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. 

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.

It doesn’t matter where you start, it matters how you end

A hero is no braver than an ordinary man, but he is braver five minutes longer.

The wise person knows that no answer is also an answer

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

If you fail, next time fail better.

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

There are no bad mistakes in maths, only discoveries.

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