I think you`re right that a schedule (relative to work tasks) does tend to be more priority based. It`s, I think, that work schedules so often are made up of tasks someone else has dictated, or the business realities demand.
It`s why I think a To-Do list should remain personal, being associated with our own "me time," and personal life, whereas a schedule would apply to working time. It`s an interesting distinction, and one I`d never paid much attention to in the past.
Apropo being self-sufficient:
For whatever reason and the things I`ve chosen to do in my life, I`ve never found mentors. My father taught me a great deal about business, although he had a bit of an attitude. I found a few musicians in the music industry who were willing or able to help, but other than that, I`ve just never met anyone who could be a guiding force over more than a very short moment.
Instead, I`ve taken advantage of boards like these, where anyone on Earth can join and nobody knows anyone. As such, it`s as close to both completely objective feedback and also looking in a mirror as I`ve ever seen.
The result is that I`ve had to learn how to go it alone, and that`s where my interest in "process" has always continued. Not only do I have to figure out how to do things on my own, I`m fascinated in the eventual solution, how it showed up, how well it works, and if it would work for anyone other than myself. To a great extent, it`s why I`ve become a philosopher or writer.
Oddly enough, when I went about defining the term "depend," it took a long time to find the opposite---the antonym. I believe the best one is self-sufficient, but I`m still working on that one. (It might better be self-reliant.)
