Definitely a discussion that warrants some talking to. As a former broke student your ability to save is directly correlated to how much you have, because let's face it, every single college student who doesn't have rich parents or a well-established wealth fund is frugal enough to survive in this hellhole. It all depends on how much money you have that you can save. Honestly speaking, I would really suggest you save first on your emergency funds rather than go ham on investments because you can easily do those when you're already earning more than what you have right now, while it is not unbeknownst to us that health risks happen at any day and age, doesn't matter if you're a student or a salaryman already, but it surely does hurt when you're still a student. In that regard, I think saving for emergency funds is much better considering your age.
At the same time there is no better opportunity than risking something when your responsibilities are still at their lowest. I do agree that you should of course be able to pay for health insurance, but if you wait too long with taking risks I can tell you that new responsibilities come into play that could again keep you from taking risks. You need to strike the right balance here.
When you say you also used to be a broke student, I think that is a major problem. Education is expensive in many places around the world and usually it is so expensive that you have to get into debt deeply. Yes it is an investment in the future, but simultaneously it somewhat narrows down your options as you can't wait and see, but often times have to pay back right when you finish your studies.
The institutional environment is built that way. In order to take on certain jobs, you have to have a degree, and therefore you have to pay tuition fees and get into debt if your parents are poor. That is why I really like the freely available information and education on the Internet, but that still doesn't get you the degree you perhaps need in order to pursue one of your dream jobs.
A smart investment can put you into a decent position for the future. But again, there are basic needs that you should still be able to cover.
