Time is incredibly short. Money is only interesting as far as it lets you spend time on things that matter to you. Therefore time spent unhappily obsessing over money is a double tragedy.

We live in an era where almost everyone in the West has access to physical and social luxuries that go far beyond the lifestyle enjoyed by kings of the past. Louis XV of France spent his evenings in drafty old Versailles playing craps with the same old boring courtiers; we've got central heating, Netflix, boundless internet communities and $5 clothing delivered to your doorstep if you want. You don't need anything more than what you already have, and you're not going to be poor by any definition within your lifetime. Probably the best way to make that concrete is to start giving money away: charity is the easiest way to feel like a king.
