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

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

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

The greatest mistake we make is living in constant fear that we will make one.

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

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

Time is your friend, impulse is your enemy.

We learn more from failure than we do from success.

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

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

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. 

Success is the sum of small repeated efforts, day in and day out.

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

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Success can never happen without the journey (struggle).
