A few weeks ago, several inches of heavy, wet snow fell. It was April, so leaves had sprouted, giving the snow more places to accumulate. And the combination of the two resulted in trees and major limbs falling all over the trails. Many were so large, they were impassible. Because I know the trails so well, I was able to quickly adjust to alternate trails. When one option is closed off, there are always others to keep going.
The same is true in business. Periodically, obstacles pop up requiring a course change. When time is spent in advance to understand the market dynamics, adjusting course can happen quickly. And that speed allows you to outperform competitors.
