Providing for future = money made (active + passive) - money lost/spent (active + passive)
So lets talk about the money lost/spent side, and one of those sirens of excessive consumption: depreciating assets. Depreciating assets are consumption posing as assets.
Depreciating assets are fun. Clothes, furniture, cars, fancy electronics, name brand purse. But they often don't pay off in the long run. A car will depreciate 25% the minute it leaves the lot. Praise and envy from your peers will but a moment. That glow cost you couple K.
Whenever I forgo a depreciating asset, I think about how I'd much rather put the money in an appreciating asset. I imagine myself reducing my 12hr days into 4 hr days, maybe in a hammock with some iced tea, maybe painting or writing a book. This is the meaning of an appreciating asset to me, not the movement of decimal places of paper profits, but the true luxury of spending time in a way I really want to spend it. Then I begin to hate depreciating assets for all their seductive appeal.
For example, my thought process in not buying a car ($20K plus insurance cost + parking). Sure I could buy a $20K car, and have a $15K asset a year later. Or, I could put this money towards downpayment on a house - $20K of car = $133K of downpayment on a house. Over time, a house is more likely to appreciate.*
*Of course, buying a car in 2007 would have been a better choice than a house in many instances.
