Why not do fads in moderation? I've always done this.

Don't convert it all to xhtml, just start closing your <tags>

Don't go full UML code generation mode, just use it to illustrate core business logic.

Don't buy an iPhone, get an n8.

Don't be a cryptobro, just get one, set it aside.

Don't go full TDD, but use it for bug fixes.

Don't go full knowledge graph/org mode, just have a captain's log.md and an assets/ folder.

Don't go full microservices, create modular monoloths.

Don't go full agent teams, just use normal cli.

etc. etc.
