Your creative output spans several disciplines - a big reason why I enjoy your work - while a goal of yours is preventing multi-tasking. Can you define what unproductive multi-tasking looks like to you vs. what have you found to be a productive way to shift your focus from one discipline to another?
It comes down to scope and granularity. The ideal focused work to me is a session of 25:00 pomodoro. Undistracted, focusing on a single task, with a single tool, undisturbed. Then, throughout the day, the relationship between each of the pomodoros, would be done for a singular project.
An unproductive multi-tasking day, would include interrupted sessions of pomodoros, over multiple unrelated projects.
In your tracking, I like that you differentiate between focused input, like listening to music, and output, like performing music. How do you decide what is an appropriate output of something you are curious about and what's your process like to allocate the right about time towards it?
