Danny! We worked together at BB :) I especially like,

  "I don't claim to actually know all that much, but everyone has something worth sharing."

I've resisted blogging for a long time for fear of not having anything to talk about, but couching it as "sharing" feels like a much better (more generous, more motivating) POV.

If you aren't currently using any "knowledge management" software, you may want to check out Obsidian or Roam Research. I bet you'd get a lot out of it.
