Shouldn't this be in Beatnik? Very cool line of thought.
Life is too short to....
...Say "I can't". Replace with the text "How can I..." and turn it into a question.
...Live in a box. It's okay to have a box to come home to, but you can't fully appreciate your box unless you know what's outside it. (Kevy, get your brain out of the gutter
this instant, and back in the sewer where it belongs!)
...Not sing. Like anyone's going to stand over your coffin and say "Oh yeah, so-and-so was a wonderful friend, but homegirl COULD NOT hold a tune!" Who the hell cares? Singing is an expression of joy, and should be done on a regular basis (like "preventing cancer"

)
