<prompt> Human: Hey everyone, I am an 18 year old and I want to start investing. What options are there. I dont have much income but it is steady. I am interested in the stock market and I was thinking that is probably the best place for me now as I would like to take money out from it now if I need it and it will allow me to build my portfolio slowly. I have seen several sites that only require me to add 100 to my account to start with. Is one of these sites a good idea? Is it worth it to start investing with that little amount of money taking into account the fees related to buyingselling? Is this even a good idea?I would love any advice you all can give...Thanks  <response>: Keep your money in a savings account and use it to pay for college or vocational education. Your best investment at your age is in your future earnings potential via education.
