Principles of Adult Behavior

  1. Be patient. No matter what.
  2. Don’t badmouth: Assign responsibility, not blame. Say nothing of another you wouldn’t say to him.
  3. Never assume the motives of others are, to them, less noble than yours are to you.
  4. Expand your sense of the possible.
  5. Don’t trouble yourself with matters you truly cannot change.
  6. Expect no more of anyone than you can deliver yourself.
  7. Tolerate ambiguity.
  8. Laugh at yourself frequently.

Clojure is for type B personalities

The other day, I was wondering why Clojure fits my brain so well. I think I was relaxing on my old couch, drinking cheap beer, eating a gas station pastry, and drawing doodles on a stack of overdue bills I forgot to pay. Little did I realize, these things are all connected.

I have a hypothesis that people choose programming languages based on their personality. For the purposes of this write-up, I’ll use the well-known distinction between type A and type B people. This may be pop psychology stuff, but it’s convenient for my point so in the spirit of American politics I will treat it as fact.

Type A vs Type B

Type A people are very organized, competitive, punctual, and like to plan ahead. When I was a kid, these were the ones who had perfect grades, competed in track or swimming, and on top of that they were nice people so I couldn't even hate the fuckers. Type B people, on the other hand, are laid back and like to do things spontaneously. Like The Dude from The Big Lebowski, they are comfortable with
