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

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

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.

You can have results or excuses, not both

If you fail, next time fail better.

Instead of finding reasons why you can't, find reasons why you can.

If you want to succeed, double your failure rate.

Start, struggle, fail, fix and learn. Repeat.

Success can never happen without the journey (struggle).

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

Your limitation - its only your imagination.

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. 

He who has begun his task is half-way done. Have the courage to begin!

We learn more from failure than we do from success.

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