Wish I had started out asking your sort of questions when I was sixteen.
Myself, my Children and Grandchildren have found wonderfull basic learning from the "Rich Dad Poor Dad" series of books.
From these books one learns the value of money itself and how you can get it to work for you passively.
You learn about (1) being the worker, (2) working for yourself, (3) getting others to work for you, and (4) making money and other businesses work for increasing you wealth, in other words being the banker.
Probably too much for you to take in in the beginning but I am sure that by working through this series of books you will be left with a feeling "that you can"
Good luck in your future life and an important point (and really think about this), do not risk your money in any investment if you do not understand what is going on or if you have any doubt about it at all.
And keep asking questions.
