notes from the q&a

  • When these combine it creates a powerful set of behaviors 
  • Watch out for these combinations they are most dangerous
  • Some of the items are overlaps and permutations of others
  • That is okay because they present a great deal of benefit
  • The ordered rational thinking suggested here is a powerful tool

  • organize your day to do unpleasant things first
  • reward yourself with things you like doing after
  • keep good records, analyize the thinking that lead to failures
  • build careful habits that serve you
  • don't go to open auctions, skip all auctions

be wary of over specialization
