You’re likely a productivity hobbyist if:

• You frequently do things like re-purpose shoeholders to organize your gadgets.
• You have a t-shirt that says “David Allen has a posse.”
• You modify your GTD system on a weekly basis.
• You’ve ever emptied your geek bag, taken a picture, and then shared the picture with friends. 
• You seriously can’t wait for the next release of Remember the Milk or Better Gmail.
• You exchange “Moleskine hacks” with your friends over beer.
• You’ve ever spoken of “date hacks,” “marriage hacks,” “diet hacks,” “child hacks,” “food hacks,” “kitchen hacks,” “parents hacks,” “brain hacks,” or “inspiration hacks.”
• Your refer to David Allen as “The David.”
• You own all of the following: a label maker, digital voice recorder, PDA, hipster PDA, a large supply of binder clips, and an ebook reader (like like Amazon Kindle or the Sony Reader.)

Yep, I am a Productivity Hobbyist, but in reality I am Mostly Organized.
