This is not a simple question. First, you are thinking about your life. Second, you are thinking about your career. Regarding the life of a college student who has just left school, I think you should work hard for your dream, because you still have time to realize it (even if possible). Otherwise, you may regret it later. As for investment, I don't think it's urgent. Before deciding whether to invest, let's make a detailed investigation. There are several ways to buy shares, some are that you participate in management as a shareholder, and you can also pay dividends at the end of the year in the form of joint-stock system. But no matter which one is based on trust, it is more important to think clearly, because you are classmates and friends, to avoid the influence of money on your feelings in the future.
