I read an interesting book which suggested that what we call luck was a learnable skill in and of itself. It suggested that luck is no more than effective noticing, and a "lucky" person is simply more likely to notice something that would be construed as lucky by a neutral third party. The book also noted that lucky people didn't win more than statistics suggested they should (they were no more likely to win the lottery), but they opened themselves to situations which allowed a win to happen, and so had more chances to win than someone who closed off their options. In case you're interested, the book is "The Luck Factor", by Richard Wiseman.
