Why hobbies are always the first thing to go
The reason is structural, and it is the same structure this library keeps finding: work arrives with scaffolding (deadlines, meetings, people waiting) and enjoyment arrives with none. Nobody chases you for the sketchbook. The band survives without you this week. No consequence lands tomorrow if the walk does not happen tonight. So in every collision between something with a deadline and something you love, the thing you love loses by default, quietly, week after week, and the person it belonged to files the loss under being busy.
The cost never announces itself, because each individual forfeit is small and reasonable. It compounds anyway. A year of deferred evenings is a hobby you used to have, and a decade of them is the version of the story where you cannot quite remember what you did for fun. None of it was decided; that is the point. The weeks that spend your enjoyment were never planned to, they just were never planned not to.
There is a second, quieter mechanism, and I think it does more damage than the deadlines. Dated things survive a busy life, just about: a birthday has a date, a gig you already booked has a date. The things you love mostly do not. Nobody searches for modern jazz every time they wonder what is on, so the evening defaults to whatever is nearest, and the person who loves modern jazz ends up on Netflix again. Not chosen, just unasked. A system that brings the undated things back up is most of what this guide is arguing for; the backlog step below is the pen-and-paper version.
