Yes, my dh is like that. We have a 1.1M but that's not enough; he wants 3 million.
He recently started buying lottery tickets because SAYS he wants to retire (waste of $$ imho). In the meantime he works more hours than ever before even though he doesn't have to (he works about 10 hrs/day). I ask him why he works so hard, and he doesn't answer me. When I REALLY press him for an answer, he tells me he's working on an interesting project at work. He doesn't make sense to me!
