in the course of may daily surfing (doesn’t everyone have a regular web route they follow every day?) i came across a post on lifehacker asking people to submit pix of their “go bag,” the messenger bag or whatever they take when they go out. they wanted to see what items and “productivity tools” people were carrying. not only do i not own anything i’d consider a “productivity tool,” when i go out the last thing i’m thinking about is being productive. am i hopelessly behind the curve? do my camera, cell phone and the current book i’m reading qualify as “productivity tools?” and if i carry them in my hands rather than a bag, do they count? and why do i care about any of this?
