If we stick with the knowledge we know we never gain an inch, so I explore my hobbies.
I do have a large selection of Marineland products as well as an assortment of small tank equipment but just owning them would do me no good without the technical knowledge I've gained from never turning away from something I don't understand.
So in a sense you hit the nail on the head, I am more a technologist than anything else. I tend to be a genius at nothing, but tenacious at exploring anything.
I can't remember many toys that I had when young that I didn't take apart to learn how they worked. Thus to keep the toys I learned to sew, solder, woodwork, paint, and repair both on the small and large scale.
