I like when I find things I held for a long time are wrong -* -
  it happens less and less, which is what I really enjoy. Each
  time I'm fact-checked (whether I do it to myself or it gets done
  to me),, I know that "what I know" is stronger now, more
  dependable. I remember as a kid being told something about
  rockets. I don't even know what. Somewhere as a teenager, I
  repeated it and got laughed at. I was confused. I went to the
  library and looked it up and found out WHY they laughed at me. I
  don't remember what it was about, except some fact about a
  rocket that was WAY WAY off-base. But the lesson remained: a)
  sometimes I'm gonna look stupid b) checking facts first helps
  prevent a) somewhat. c) checking facts afterwards prevents a) as
  well, for future encounters..
