From east to the west

In a narrow path like this, the longer one treads on, the more one receives. When one chooses to go an extra mile; one receives, and where one decides to stop, there is no net gain or lose. There is nothing, when one decides not to do anything, yet it is a gain, when one chooses this over better-than-nothing. It is no longer about giving is receiving. But the amount one "loses", when there is no input, compared to net gains, and losses.
All the way to CC16? Isn't one very exhausted? No, the longer one sets to stay on this path, the more one receives.
