Mark Forster has posted his Simplest Time Management Method.
I discovered that all I had to do once I’d drawn the list up was to draw a line at the end of it. Then I continued to add new items to the end of the list but didn’t allow myself to work on them until I had finished all the items up to the line. I could do those in any order I liked.
Once I’d finished the items above the line, I drew another line at the end of the new items and did the same again.
I like the simplicity of this approach. You get everything in the list, and you give yourself a basic rule that prevents leaving those tasks-I-don't-want-to-do behind. And you can still feel like you are getting things done.
