I'm a jack of all trades, and I tend to try and perfect my 2D first. I'm a semi-professional (educated) Graphic Artist with degrees mostly in logo design and print atm. I'm learning video editing (not hard) and a little web design (which I've already known for a while) and will have a Digital Media degree soon for sound and video mostly.
I'm self-taught in 3D works which I rarely had time for before and only dabbled a bit but have retained what knowledge I had in it...I also made 2D games for a little bit using various engines including one I built myself. Nowhere near perfect quality but it worked none-the-less.
I suppose you could say I'm in the same boat but I am going to school to fix that and I am focusing on one area at a time.
most of the stuff you list here is somewhat related to each other - I go all over the place.
Truckdriver by trade...which means I not only drive, but check & maintain the truck/trailer, play bookeeper, puplic relations manager, scheduler, etc...
Self Taught Mechanic - and fairly good at it if I do say so myself... *winks* (now where is that winky smilie??) if it isnt too computerized, i can fix it (dont have the diagnostic tools for the newer stuff)
Know enough about computers that friends call me when they are having a problem (and if I dont know, I know people that do)
I have some formal training in both graphic arts & drafting, but never finished school
art - again, all over the place! have tried just about ALL traditional mediums including photography which led me to computer editing, etc
and then there are the "household" type things - I can do framing, drywall, electrical, plumbing - pretty much anything - and do it well enough that it would pass inspection by pros
hmmm...maybe I have ADD?
