The idea of working linearly. You take one direction and just execute in it.
Examples:
- Edit pages in order, trying to bring each to closure instead of leaving stuff for another pass.
- Clean a surface from left to right, instead of by category.
This way, you minimize thinking time and all your focus is on execution. Otherwise, your mind is prioritizing work and the moment I let my mind prioritize, it tricks me into thinking and not doing.
