I'm good at certain things. What cool stuff can I do with these skills?

Shamehole Management which is what I sort of do "for fun" with friends who are in over their heads with big houses and too much stuff. I go over and help them take a roomful of stuff and turn it into junk, plastic boxes of stuff and things to use/sell/admire. It's super fun. There are also more formal professional organizers and also people who just help people do estate sales and/or clean out hoarder houses. Some of this depends not on your skills as much as your personality when using those skills. Also you could be an archivist or even someone in records management. Again, some of this is personality based, whether you'd like making use of your skills in this way.

You could study industrial design and industrial organization.

My friend has similar skills and in the past two years he's gotten really into woodworking. Specifically dovetail joinery, which is this whole thing. You also might find particular pleasure in origami. Do you know about http://kusudama.me/? The best helping-other-people thing about your skillset is tetrising things into other things. I bet you can pack a car trunk like nobody's business. Offer to go on ikea trips with your friends and help them fit the boxes in the back seat. You'll be as a golden god.

Well, Project Management is one thing. Remodeling is another. Remodeling requires attention to detail, ability to coordinate a number of activities simultaneously, and to insure that things A, B and Q are done and finished in time to start W and Z. So maybe you'd want to do some building with Habitat for Humanity to see how it all pieces together.

I think you could be a part-time professional organizer. People will pay $50-100/hour for those services.

Some ideas: Model-building, woodworking, sewing, organizing tupperware, winning guess-my-weight games at the state fair, parking in tough spaces, backing up with a trailer...?

Oh also if you don't want to be a full-on professional organizer, you could probably pick up some odd job gigs just by asking around. The family I babysat for used to hire me to pack the kids for camp, organize the mom's office, help the Grandmother organize for a move, etc.

Aviation. The skills you describe are all critical to aviation. Get your pilot's license!
