Answers for me: > Why didn't you do those things? Because at that time I was a child, and thus simply wasn't able to, even though I saw the potential. > Why aren't you trying to catch the next trend? I actually attempt to, but since I have an exhausting job, I can only invest very little time at night and weekends on this topic. And no, my (also work) environment is not very receptive to my ideas ... :-( So, what I do is rather attempting to catch some long-term future trends. But I am very sure that I am onto some something(s) since when I presented some of my ideas to my former PhD advisor a few months ago, he immediately made slight attempts to (re)hire me. Well, a few years ago, I would likely have taken such an offer, but now I am not anymore willing to accept the bad job security and prospects in academia (which were central reasons why I left academia).
