Does this sound like the set of challenges you might be facing?

  • The stuff I’m most certain I’ve nailed is exactly what blindsides me on the test
  • The areas where I feel most sure and think "oh this is obvious, I’ve got this" are turning out to be exactly where I get blindsided
  • I’d jump on this in a heartbeat if it were the familiar version, but because it’s in a world I don’t know I’m demanding way more proof before I’ll touch it
  • There’s one area I consider myself an expert in, and that’s exactly where I’m most stubbornly sure and most often wrong
  • Once I believe something, I only ever notice the things that prove me right
