Remember this IS a hobby and to each their own. As an engineer, I do model and design what I use. I hate the “by guess and by golly” approach. Everything I do is carefully planned in advance and is a part of my enjoyment of the hobby but YMMV.

Back in the day, you put something up and experimented from there -- making contacts along the way. Now, folks look at the internet and then second guess everything they read to the point of information overload and analyses paralyses.
