In plain words, play DIFFERENTLY from others, AND from your old self.

When a weaker force fights a stronger force on the same battleground using the same strategy, the underdogs' chance of losing is around 80%.
If they fight with a different strategy, their chance of losing goes lower than 40%.
And among the underdog losers, 80% never switched strategy.

Keep many ways of winning. And keep swithcing from one strategy to another.
