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

Nobody said it’d be easy, they just promised it would be worth it.

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

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Yesterday is history, tomorrow is a mystery, but today is a gift—that's why it's called 'the present

Shoot for the moon and even if you miss you’ll land among the stars/

We learn more from failure than we do from success.

Do what you have always done and you will always be what you have always been

If you fail, next time fail better.

Hope might be a good breakfast, but it makes a very poor dinner

It always seems impossible until it's done.

There are no bad mistakes in maths, only discoveries.

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. 

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

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