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

It is never too late to become what you might have been

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

Failure is not the opposite of success, it is part of the success.

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

The easiest person to deceive is yourself.

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.

Go as far as you can see, when you get there, you’ll be able to see further

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

99% of genius comes from hard work, the remaining 1% comes from innate talent

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

The wise person knows that no answer is also an answer

No matter how bad it gets, you’re still way ahead of those who haven’t even started.

Skills are built not born.

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.
