Money isn't the only value. Some would argue time is more valuable than money.
My grand daughter visited us over the holidays. I took a gazillion photos and videos until it hit me...jpegs are not scarce, but time spent with the ones you love is scarce.
If you limit yourself to 36 shots, you limit the time you spend with your technology and maximize the time you spend with your loved ones.
You spend time waiting for your kids (or grand kids) to laugh or smile to get the perfect shot, but that means you're focusing on the kids and not the screen.
Using a 35 mm camera isn't such a bad idea.
