Your 'free' time is valuable currency, and every minute must be invested as productively as possible, or you'll lose to someone else who does in this kill or die monkey knife fight economy [https://slatestarcodex.com/2014/07/30/meditations-on-moloch/].

"So be it with Gnon. Our job is to placate him insofar as is necessary to avoid starvation and invasion. And that only for a short time, until we come into our full power."
To give everything of yourself over to Gnon/Moloch is to deny Elua, who Scott names the god of art, science, philosophy, love, niceness, community, civilization. One might add to that: the god of play, of gardening – of reading.
Free time is for enjoying life, doing things you love, spending time with loved ones,... Not everything has to be about ones productivity.
Our time is way too short to spend everything producing things that will likely be forgotten or not used anymore in 75 years.
We must not forget to live life.

I've read that twice now. Just as interesting, funny and depressing both times.
