I think better advice would be “invest/save” in general. You could just throw money into a mutual fund, index fund, savings account, whatever. If you get a job with an employer matched 401k, max that out. I don’t think you need to worry about trying to play the stock market by buying individual stocks. You’ll end up spending way too much time doing it for minimal gains over an index fund, and a lot of the time you’re just basically gambling on what companies you think are going to do well.
