In order to achieve any result, you must be willing to accept its opposite.
For example, if you want to get to California from the east coast of the United States, you must go west.
But if you’re completely, obsessively, unbendingly attached to the strategy of “going west,” you’ll never reach your destination. Why? Because inevitably you’re going to run into a river, a mountain, or a dead end.
When that happens, you’ll have to adapt. You’ll need to go south or north, or maybe even east. “East? Travel east!? But that’s literally the opposite of what I need to do!!!”
