This is a great article and you make a good point, but how can one reverse the fortunes of the unfortunate people that have been facing a lot of losses per se. You mention MJ and Lincoln, and I love them both, but doesn't what you say go against the article then? These men faced a lot of failures - thus lost a lot - thus likely had the reverse winner effect - HOWEVER turned out to be extraordinarily successful. True they had grit and it seems to me that it is the only method of reversing the misfortunes of failure.
The tips given at boosting dominance may be great but is grit the only way to break out of the loser's cycle?
