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. 

The journey of a thousand miles begins with one step. 

Success is a journey, not a destination.

Success is the sum of small repeated efforts, day in and day out.

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

Tough times never last, but tough people do.

Hard work - a two way street where you get exactly what you put in.

Hard work beats talent when talent doesn't work hard.

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

Procrastination makes easy things hard and hard things harder.

It doesn’t matter where you start, it matters how you end

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

There are no shortcuts to any place worth going.

Skills are built not born.

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