Personally both my wife and I are happy with the priorities we have and memories we are making by the way we spend the amount of "fun" money we feel is discretionary. Honestly, once you pay for food, shelter, and clothing everything else is "fun" money and I'd rather spend it on sleds than I would on "a hot woman".
I have a friend who is a CFO, he bought a brand new sled a few years back, it was the first time he owned a sled. After he bought it, snowmobiling was never as much fun for him. He sold it 3 years later. When we talked about it he said he just couldn't get the ROI he expected out of it. That was the problem right there. If someone judges "fun" in the same way they judge investments chances are they will never truly leave their cares behind and just have fun.
