This one teaches you to build tools for yourself first, then maybe share them later. It covers the full arc from quick script to actual product: CLI tools with Commander or Click, local-first apps using SQLite or JSON files, and knowing when a personal tool is worth polishing for others. The approach is refreshingly practical about starting ugly and only improving what you actually use. Includes concrete patterns like the 10-minute itch test and evolution stages from hardcoded script to public tool. Best when you're tired of doing something manually and want to automate it without overthinking whether anyone else will care.
