Since I got a worf for my hobby reply I just wanted to clarify, I wasnt being dismissive. I didnt appreciate college when I just got out of high school. I fucked around a lot, didnt bother doing anything and quit after two years. When I grew up a bit, I finished that degree (Economics) and realized there were certain classes, particularly math, that I enjoyed. Since I barely work, and what work I do is almost entirely up to my discretion, I decided to start taking a class or two a semester just for fun. This was 12 or 13 years ago and I have not stopped taking classes, sometimes more than 1 or 2 a semester (last semester I took 6 which wasnt smart lol) and the topics of interest to me have widened from just math to pretty much all STEM fields (except chem, eat shit and die chem).
Now since I have been at this for over a decade, I am more or less out of classes to take so a large portion of what I do involves independent studies with Professors to either work on some shit they want me to study or projects that they need done or are interested in exploring. There have been a couple of things that I myself have requested the Professors take an interest in and I have done study under them on those topics.
The tl;dr is that by going to school I have access to people much smarter than I am and the ability to work with these people is preferable to what I was doing before with my free time.
