The journey of a thousand miles begins with one step. 

Nobody said it’d be easy, they just promised it would be worth it.

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

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

There are no shortcuts to any place worth going.

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

You're not in competition with anyone but yourself. Outdo your past, not other people.

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. 

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

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

The journey of a thousand miles begins with one step.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

The road to success is like a staircase. If you want to succeed, double your failure rate

The bad news is time flies, the good new is that you're the pilot.
