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. 

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

Practice like you’ve never won. Perform like you’ve never lost.

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