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. 

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Go as far as you can see, when you get there, you’ll be able to see further

I can is 100 times more important than IQ.

Don't fear failure, fear being in the same exact same place next year as you are now.

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

You cannot escape the responsibility of tomorrow by evading it today

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

The wise person knows that no answer is also an answer

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

There are no bad mistakes in maths, only discoveries.

Success can never happen without the journey (struggle).

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

It always seems impossible until it's done.

No one starts out on top. You have to work your way up.
