I'm not a GTD freak; I've never read the David Allen classic. However, that does not isolate me from being a Productivity Hobbyist. My fascination with lifehacks and shortcuts is very much on the level of a hobby. It is certainly not out of necessity. If I were to spend as much time doing work as I do reading about how to do it quicker, I would get much more done. However, when it comes down to the deadline and getting things done, I can usually (due to my hobby) zip through a list of tasks with ease.
My hobby is not entirely in vain. I've been able to stay ahead of many of my more knowledgeable co-workers when it comes to workload, simply because I've discovered tips, tweaks, and hacks they haven't.
I'm quick to give up any secrets. As soon as I come across a piece of information that I think is valuable, I want to share it with someone else. I want to constantly be a learner and a teacher. In many respects, I want to be a filter. I'll read 30 blog posts a day on productivity, and I'll pass along 3. Not that the content of the others wasn't valuable, but I'm intentional when I forward the 3 filtered posts.
My productivity hobby is primarily centered in the world of technology. In the coming weeks, I'd like to discipline myself to actually post about some of the tools that I use and how they make my life better and more productive.
