This probably means that the choice is yours. Your the author of the script of your life because you get to write your own story and make your own choices. Your the captain of your ship for the same thing. You sail wherever you want to lead your life too/
Ummm select what??? there's nothing but a question
The answers honestly vary but I'll say.
Temperature (degree of heat and cold)
Winds (their movement and direction)
Rainfall (its causes and its seasons).
In my opinion, the second main argument in "The Human Drift" is that human wandering across the planet, back and forth, has always been fueled by fear, while motivated by the search of food (as the first argument says). It is a primal fear that, if you don't eat, you will end up in someone else's stomach. Here is a nice excerpt that illustrates this argument: "Dominated by fear, and by their very fear accelerating their development, these early ancestors of ours, suffering hunger-pangs very like the ones we experience to-day, drifted on, hunting and being hunted, eating and being eaten, wandering through thousand-year-long odysseys of screaming primordial savagery, until they left their skeletons in glacial gravels, some of them, and their bone-scratchings in cave-men's lairs."
