If you fail, next time fail better.

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

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.

Fall down seven times, stand up eight.

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

Skills are built not born.

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

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Success is not final and 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.

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

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

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

You can be shown the path, but only you can make the first step.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.
