  Maybe I only had to make 1 or 2 angel investments (and not 5) to learn what I did?

That bullet point stood out because it reminded me of a passage from "Reminiscences of a Stock Operator":

  It cost me millions to learn that another dangerous enemy to
  a trader is his susceptibility to the urgings of a magnetic personality when 
  plausibly expressed by a brilliant mind. It has always seemed to me, however, 
  that I might have learned my lesson quite as well if the cost had been only one 
  million. But Fate does not always let you fix the tuition fee. She delivers the 
  educational wallop and presents her own bill, knowing you have to pay it, 
  no matter what the amount may be.Having learned what folly I was capable of, 
  I closed that particular incident.

Sometimes you just have to pay your tuition.
