From http://www.markforster.net/blog/2011/2/10/rules-for-superfocus.html:
SuperFocus is a very simple but effective method of processing your work. You write everything you have to do in a long list in a notebook. As you think of more things you add them to the end of the list.
Then you start at the beginning of the list and keep circulating round the first page, working on the tasks until you have worked on as many as you want to. Then you move on to the next page and do the same. Once you have got to the end of the list, you go back to the beginning, and start again at the first page.
I like the list-based approach to decision on tasks. What software could I use that'd be best adapted or has already built-in support for SuperFocus?
