Henry Rollins has a spoken word presence that is not to be missed, in my opinion. He gets up on stage with a microphone, takes a fairly aggressive and active physical stance, and just goes... for hours. When I saw him for his first stop on one of his tours, there was a bottle of water near the base of the mic stand that remained untouched for the entirety of the show.
While it may seem a bit jarring to read him going on, at length, it's sort of what he does these days.
"Knowledge without mileage equals bullshit."
The guy lives a very interesting lifestyle and a great deal of what he practices and preaches is highly applicable to the entrepreneurial spirit and existence. Pretty stoked to see him on Hacker News.
