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.

Everything you want is on the other side of fear

There are no shortcuts to any place worth going.

The greatest enemy to human potential is your comfort zone

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. 

Your attitude is everything. Pick a good one.

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

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

Practice like you’ve never won. Perform like you’ve never lost.

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

You cannot escape the responsibility of tomorrow by evading it today

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

99% of failures come from people who have the habit of making excuses.

Hard work - a two way street where you get exactly what you put in.

Don’t be afraid to work hard and find out how good you can really be.
