Okay, let's do a checklist version.
1.change a diaper- Yup.
2.plan an invasion- Probably. Never tried anything bigger than taking down a paintball base, though.
3.butcher a hog- In theory, yes, but I'm a vegetarian, so I probably have to pass on this one.
4.conn a ship- Basically. Not too sure about sailboats, though.
5.design a building- To the point of having walls and a roof and a floor that stand in concert, yes. Don't know if anyone would actually want to *live* in it, but... ;)

8.build a wall- Yes.

16.analyze a new problem- Tend to enjoy it.
17.pitch manure- Don't particularly enjoy, but yes.
