Okay. You'll need to start with some basics.
A) You need financial goals. These are the big pricey things in life. Houses, retirement, living on a boat in the Gulf...etc.
B) You need to figure out how you will afford these things. Most people do it by saving. So a big step in attaining your goals will be by spending less now to afford more later. So saving a good deal of money is very important for all your future goals.
C) You need to know what investing is. I'd start with reading a quick guide on stocks by
