I feel and think much as you do, care about many of the things you care about, although most do not care about them. You are not alone.
Me: 30. Urban planner during the morning and early afternoon, mid-handicap golfer in the late afternoon, and dedicated bookworm and craft beer drinker in the evening. Sometimes I write stuff, too. Just figured out that Hemingway and Vonnegut are geniuses. My worst quality is that I live in Ohio.
You: A real-life version of Franny Glass. Existential nervous breakdown negotiable.
