A book a day keeps the stupidity away.

Instead of finding reasons why you can't, find reasons why you can.

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. 

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

I think, therefore I am.

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

If you fail, next time fail better.

The journey of a thousand miles begins with one step. 

We learn more from failure than we do from success.

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

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

We are all maths people : step 1 - do maths and step 2 - be a person. 

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.
