I live frugally, and I feel like my accumulating wealth is a laser cannon strapped to my back, ready to deploy as I see fit. The freedom is exhilarating.
Just a word of advice that you may already do. Please have very good communication with your wife about financial matters. This situation is very stressful for the frugal person, and it has caused all of our biggest arguments. The only thing we've found to help is very clear communication.

What's the plan?
The post sounded to me like the Smith and Wesson retirement plan.
I have a morbid, but sneaking suspicion that that it's the latter half of "live fast, die young." Maybe I'm just projecting, though ;)
His frugal wife's savings maybe...? I hope not.
And as I've put in the effort to be more mindful of my spending, it's felt more liberating than anything else. All this to say, you might also find it can actually feel better to do other things with money than spending it.
