Do what you have always done and you will always be what you have always been

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

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 temptation to quit will be the greatest when you are about to succeed

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. 

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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.

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

If you can understand just one thing thoroughly, then you will understand everything.

It is never too late to turn an unproductive day into a productive one.
