It’s frightfully simple.
1. List the tasks in the chain.
2. Note the feeling/environment most conducive to beginning each task.
3. Note the feeling/environment which tends to follow each task.
4. Optimize order for least possible friction between tasks.
Example: Let’s say that before bed, I have to go to the bathroom, brush my teeth, make tomorrow’s food, and decompress (fairy tale reading). The toilet will call when it’s ready and doesn’t appreciably affect my mood, so I just let it be. Brushing teeth is best accomplished when I’m already running in autopilot, and leaves me feeling wound up. Making food is best accomplished while wound up and it puts me in autopilot afterward. Decompression is best accomplished when I’m wound up, and leaves me feeling sleepy. These observations suggest the following chain:
This is a pretty labored example, because the idea is pretty simple once you get it, and you won’t have to write all of this down formally unless you’re homo sapiens-level retarded.
