**Update:** This article was written in 2011. An updated description of OmniFocus’s role in my Getting Things Done system [can be found here.](/2014/11/10/a-two-context-approach-to-gtd-with-omnifocus/)
Recently getting access to the alpha version of [OmniFocus](http://www.omnigroup.com/applications/omnifocus/) (which, by the way, is going to be the ultimate GTD application) provided a good opportunity to re-assess my personal productivity.
Over the past months, without being able to pinpoint a precise cause, I’d begun to sense myself becoming less and less productive. Although somehow there never seemed to be enough time in the day to get everything done, the actual amount of useful output I’d been producing seemed to diminish.
