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. 

Failure to prepare = preparing to fail

You can have results or excuses, not both

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

The bad news is time flies, the good new is that you're the pilot.

He who has begun his task is half-way done. Have the courage to begin!

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

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