John Perry Barlow  is an activist, writer, former lyricist for the Grateful Dead  and co-founder of the Electronic Frontier Foundation . He’s also an engaging Twitter-er  who gets my attention with concise, insightful original tweets and great quotations.
In the last few days, he’s been tweeting a selection of “Principles of Adult Behavior” from a list he apparently first wrote up when he turned 30. In an article from 2001  about the perils of America’s relentless and destructive ‘pursuit of happiness,’ he writes,
But not until I turned 30 was it made obvious to me that my wariness of the pursuit of happiness might be a subtle form of treason. Like many of my generation, I hadn’t really expected to live to such an age. I really didn’t trust anyone over 30 – and remain reluctant to do so even now – but since I was about to be one, I figured I ought to at least take a stab at graceful adulthood. […] So I spent the night before my 30th Birthday composing a list of advisories to myself that I called “Principles of Adult Behavior.”
Having turned 40 myself last year, graceful adulthood is certainly on my mind (maybe more so now than when I was 30), and I find Barlow’s principles quite excellent so far (even if he himself calls them “blandly inarguable, the sort of platitudes Polonius liked to lay on Hamlet”). Navigating my way through the frequently difficult and dysfunctional world of work, these seem like good occasional reminders for being mindful, present and staying on track with good behaviour that doesn’t compromise me or others.
