We all have two lives. The second begins when we realise we only have one. 

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

Pure mathematics is in its way, the poetry of logical ideas.

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

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

Success is not final and failure is not fatal. It is the courage to continue that counts.

We learn more from failure than we do from success.

The gift of imperfection - let go of who you think you're supposed to be and embrace who you are.

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

I can is 100 times more important than IQ.

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

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

Success is a journey, not a destination.

Lose an hour in the morning and you will spend all day looking for it.

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.
