It always seems impossible until it's done.

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

"I" not them. Be the best version of you.

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

I think, therefore I am.

Everything you want is on the other side of fear

Just stick with it, what seems hard now will one day be your warm up.

Fall down seven times, stand up eight.

Hard work beats talent when talent doesn't work hard.

Pure mathematics is in its way, the poetry of logical ideas.

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 not final, failure is not fatal.  It is the courage to continue that counts.

Never underestimate the importance of small steps. small steps = big changes. 

Run in the morning before your body figures out what you're doing

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.
