I'm a technically minded person (and a guy) and I take no joy in being hyper-precise with my coffee making, yet enjoy coffee a lot. Good beans that I grind myself in a sub $30 grinder, measured by eye and brewed in the drip-over is better than most coffee I encounter and consistent enough. I don't see much point in getting fancier with it. I have other hobbies to nerd out about with better "returns" on the obsessing. Side note: yoga is pretty enjoyable, you should give it a go, maybe.

I'm a bit of a non-conformist generally, so maybe my view is skewed, but I think a big part of the "X people like Y" pattern you see and refer to is that many people just aren't practiced in trusting their own feelings and senses to develop their own preferences: they see people like themselves, and they align, and conform, often unwittingly. They join the [let's say] goth clique in high school, and then come to like mostly the same things as the rest of their clique, not only by nature or coincidence, but by a mostly subconscious desire to belong. It applies to things like gender and profession, too.
