<prompt> Human: My dad has a very good job and makes a lot of money, and he decided it would be a good idea to have me learn how to trade stocks so I can make some money for college. The problem is that I am 15 years old and dont know what Im doing. He wants me to learn about stocks so I can invest and make money, but Im worried Ill lose the money. What are some basic things I need to know to make the most of this situation?  <response>: Throw the money in a Three Fund Portfolio...then use a dummy portfolio to practice stock picking for fun.
