Make a new strategy to win the fight. We as the readers are attracted to the tales of one sided fights where the smaller side wins against all odds. In real life however, we often skip over the odds, and assume that they are stacked against the opponent. In reality, the same place where they get that power, is also their weakness.
You rarely win a fight if you play by the stranger opponents rules, that's why the underdogs always assume that they have to play it by their rules. Furthermore, to win as an underdog you need belief that you can win – and this often comes from having a better reason.
Ivan Arreguin-Toft studied all the wars over the past 200 years.When he looked at one sided battles, he realized that the better off country had a 70% chance of winning the fight. Then however, he looked at where the smaller country fought with irregular tactics, he found that they won more times than lost. In this case, the underdogs win in 2/3rds of the time.
All in all, this thought provoking book brought up some very interesting questions that truly inspire me as a reader.
