Sounds like my DH. A few years ago he was hanging towel holders in the bathroom. Tapping on the wall he says here is a stud. I have a row of holes 1 to 2 inches apart across the wall next to the towel holders probably 8--10 holes. At least they have stayed on the wall! I think he finally found the stud.
He fixes nothing unless it takes duck tape or binder twine. lol
