Back when I was still practicing, I would occasionally run into a client who had plenty of money but was worried about leaving some/all of it for their children or other "heirs." These were usually older folks who had been frugal their entire lives - they always had what they needed but nothing that they saw as frivolous or fancy. Oftentimes, their "heirs" didn't give a ---- about them, they just wanted the money. My advice to them was that they had raised their children, paid for their educations, food, doctor bills, etc., etc., and they had sacrificed to do it. The best thing they could do for their children was to teach them how to make their own way in the world. Either they had already done that or it was too late to start. They owed their children nothing beyond that. If they wanted something and had the money they should buy it and enjoy it. Their goal should be to spend their last dime on their last day.
I do not advocate reckless spending. I do advocate using one's money to enjoy life within reason. You're the only person who can decide what's "reasonable." I have never bought fancy cars, snowmachines, motorcycles, etc., but I have bought and sold a lot of guns. That's because I enjoy them and, usually, I can afford them. Honestly, my tastes aren't that expensive. I would love a nice Rigby stalking rifle in .275 Rigby but, for me, that just isn't "reasonable" even though it might even be a good investment. My other suggestion is that if you feel the need to pass assets on to your heirs, give it to them while you're still alive. At least you'll get to see them enjoy it even if you won't yourself.
