I did that too at your age Aderhammer. I built an Edison phonograph, telephone system, arc lights, lasers, holograms, 6' solar furnace, Tesla Coils, scale model roller coaster, model railroad with the working signals and scratch built buildings and stuff, Rubik's type cubes, human powered vehicles, and other projects. I'd say that messing around in the shop has served me well in my career. I always had something going, even before I got real tools. You can't have too many cans of springs, gears, switches and wires, or whatever. If you can think outside the box and utilize the skills and knowledge you gain from messing around with stuff like that, you will always have a job, and will always be ahead of those that don't.
