I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

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

Success can never happen without the journey (struggle).

Success is a journey, not a destination.

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. 

I can is 100 times more important than IQ.

I have not failed, I've just found 10,000 ways that won't work.

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

The power of reflection is the most powerful skill you’ll learn.

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

Hard work beats talent when talent doesn't work hard.

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

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

Success is the sum of small repeated efforts, day in and day out.

We learn more from failure than we do from success.
