JJMom's, I have a sneaking suspicion your version of "decent" is most people's version of outstanding. That being said, I'm pretty much the same way: short-term obsessive? It's as if I have to drain something dry as quickly as possible (be that hours for a book or months for some scholarly topic) then toss it aside. I do come back to some topics again and again, but my chronic indecision has definitely been problematic in my adult life. So, Cat, I'd ditto what JJsMom said -- bredth is fantastic, but make sure he's learning perserverance, too.
