Taking money off the table

There's a crucial extra factor that isn't in the original article, but ought to be: Money's ability to buy great experiences decreases as you get older. I've seen this with beach vacations, road trips to see a favorite band, fast cars, ski trips, etc.

Seize the moment, friend! What you can do NOW with that 10% slice will never exactly be on your possibilities map again.

I think you're hitting on something that very rarely gets discussed, at least in the US and maybe some other Western societies. I wonder if it's just simple depreciation or compound depreciation (or whatever the opposite of compound interest would be).

Me finding the money to climb Kilimanjaro at 23 is different than me having the money at 40 but worse knees.

Thank you for pointing this out and I hope someone formalizes it more.

Die With Zero by Bill Perkins talks at length about this concept (it's a nonfiction book, so suffice to say it could've been an essay.)
