I had a business class in high school in the 1970's, where we were to invest a "fake" $200 in the stock market, after the teacher gave us a few pointers. One of the students, who had a job, actually invested $200. He put it all into a local power company, and never took it out. I talked to him recently, and it's worth about $16K. His only comment beyond that, was he wished he had taken the $2500 he had saved at the same time to buy a car, and put it there, as it would be worth over $200K now!
