> Skipping days breaks momentum: I can't skip days

This is my most important rule. I do not believe in "rest days" anymore. They are catastrophic for my ability to stay focused on a big project. This isn't to say I advocate for a 997 working hour system. I do believe in taking it easy and sometimes putting in the bare minimum, but a day with absolutely zero progress I cannot permit anymore.

24 hours is a long time. If I can't add a tiny amount of value each day, the project is probably dead. Especially a project like a game. The workflows for things like creating 3d models and scenes are generally so complicated that if you don't exercise them ~daily they will rot quickly. I open blender after not using it for a few months and it almost feels like I've never used it before. Not because I don't know how to use it (although I am far from an expert), but because the specific workflow that adds value to my project is not a straight line through space. It's a lot of steps and menu options to click through. Good luck remembering which UV unwrap presets you prefer for UV0 vs UV1 after a week of working on something unrelated.

Just keeping the tool chain open & alive on my machine feels like 80% of the battle. If it's sitting there and in a good state to iterate with, I find myself automatically pulled toward it. If that battlefield 6 queue takes longer than 10 seconds, I will inevitably be alt-tabbed into Visual Studio or Unity.
