In the other examples at the bottom tucked in there is a great example of how seemingly negative things can actually turn out to be a positive thing, this example is talking about the board game chutes and ladders.

  I explained the seemingly paradoxical situation where it is 
  possible to add additional chutes to a game board and 
  reduce the average length of a game! How come? Well, if you 
  have a long ladder in the game (such that landing on one 
  will propel you far up the board for a strong advantage), 
  and you miss it; If the added additional chutes on the   
  board send you back to before this long ladder, then you 
  have a second attempt to hit the long ladder!

wow- I love this, it supports the notion to 'fail early' in business
