I'm online right now reading that article you linked to and now reading thru websites on figuring lens sizes based on sensor size..

My pocket camera has manual settings and years ago, I did a little google searching and figured out what I needed to do to take a nighttime photo of the house with an open shutter, (forgot all of that information already), so I setup a tripod from an old telescope and took a few photos over the span of a couple of weeks. They were okay and nothing spectacular, but it was fun to see the camera do more than what the pre-set settings allowed it to do and it was fulfilling to apply some knowledge and see it actually work in person.

I currently own a business that I opened without any prior professional experience in and it's fairly successful. I brew beer for a living and most folks have no idea the amount of detail, mathematics and science that's involved in a batch of beer and that's fine, but i've gotten loads of questions over the years from people getting into brewing and asking questions about certain things in the process and the answer is usually way over their head, because I don't want to give them half the information..

I'm slowly learning this photography stuff is very similar. It takes some studying to get the numbers down for specific things, if you want to do it correctly, and I feel like some of those folks early-on in the brewing hobby, asking about stuff that takes years of experience to learn OR boatloads of research and comprehension.

Anyway, we're in the process of selling the business, so I'm thoroughly excited to have a little more free time and freedom and this picture taking has kinda gnawed at me since I was young. I've still got my parent old Pentax 35mm film camera, as I kind of hijacked it from them at some point many years ago.
For whatever reason, maybe cause I'm outdoors and always looking around, it seems like taking a nice sunrise or sunset photo, or some nature photo has come easy to me, and since I enjoy it, I guess I should pursue it and see where it goes.

I've been brewing beer to try and enhance and brighten people's days, I find taking awesome photos for folks to enjoy even more rewarding.

I'm prolly going to go the safe route (less money) and go from there, but, after reading your reply, I think I'm going to get familiar again with that lil pocket camera first. Sucker is paid for and I can re-learn some of this stuff on it.
I know the sick feeling you mentioned. I've put myself in that spot multiple times recently

I sure appreciate the info, opinions and wisdom! This is fun to talk about.
