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

Everything you want is on the other side of fear

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

Fall down seven times, stand up eight.

The journey of a thousand miles begins with one step. 

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

There is no elevator to success, you have to take the stairs.

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

There are no shortcuts to any place worth going.

You cannot escape the responsibility of tomorrow by evading it today

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

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

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

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

You can hire a tutor but you can't hire someone to practice for you.
