We all make mistakes. What matters is how we choose to move forwards from them.

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

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.

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

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.
