I wonder if you have a lot of people within your social bubble who are into investing or not? In my bubble, others have only started getting interested in the last 2 years or so. By the time I bought my first CEZ stock years ago, most of them were knocking their heads.
Come to think of it, probably almost nobody. I either meet people who are into investing and fianancials at a meeting or some conference/workshop.
There aren't many of them, but I try to motivate my close friends to do it and it seems to be gradually starting to make sense to them.
In college, my circle of people is literally obsessed with investing :)
