If you go through the high grass where the elephant has already gone through, you don't get soaked with the dew.

An elephant is far bigger than the grass. When it walks through, it knocks the wet stems aside and leaves a flattened trail behind it. Anyone walking in that trail stays dry.

The lesson is sitting right there in the picture. Somebody has already done the hard part, and you are allowed to use that. The person who did a job before you has cleared something — a route, a mistake, a cost, a rule nobody ever wrote down. Walking where they walked is not laziness. It is the cheapest lesson available, and refusing it is expensive for no reason.

There is a second half to it, and it is easy to miss. The elephant does not stay dry. Whoever goes first takes the wet, and the thorns, and the cost, so that the trail exists at all. That is worth remembering before you dismiss the person ahead of you — and worth remembering if you are the one in front.
