I think most folks as they get older simply outgrow the need to acquire more "stuff". I believe by the time we reach retirement age our house and garage are already full of "stuff", and we have so many things that were starting to understand that those "things" have brought us little or no happiness and in fact are starting to weigh us down.
I mean think about it, we started out our adult life in a one-bedroom apartment trying to sleep on a freezing cold waterbed laying on the floor, reclining "in a beanbag chair watching a 13 inch television sitting on a box, and driving a 12-year-old car that burned a quart of oil a week.
And we thought how happy we would be once we owned our own home, a 21 inch television, a heater for the waterbed, and a car but didn't require jumper cables to get it started every time we wanted to go somewhere.
so here we are, 30 pounds heavier, living in a three-bedroom house, sleeping on a thousand dollar mattress after learning that no one over the age of 23 should sleep on a waterbed. Watching a 60 inch television, Driving a car that does everything but drive itself, And a garage so full of stuff the car won't fit in it.
But are we happier??? I would say probably not. Our life is more convenient now but is it happier? I doubt it. If it were we wouldn't be constantly referring to "the good old days".
So the answer is obvious. All the "stuff" we've acquired over the years didn't make us happy in a house that's nailed to the ground and it won't make us happy in a house on wheels.
Like I said earlier the more stuff I get rid of the better I feel. I realize I've still got a long way to go, after all I've got a storage room full of "stuff" that has to be dealt with someday. But whenever I look at all of my boxes it's not wistfully, it's with the anticipation of how happy I will be when it's all gone.
