Truly, the way the ideas presented is just like having a rumbled picture puzzle. But in the end after getting those rumbled ideas connected, you can eventually create a wondrous image, an image probably what the author is thinking during his time.
We live in a world full of “man”. Everywhere you go, whatever you do, or how do you do things, you cannot deny that you do not live alone, that is, you have to be a man. Humans are by nature social beings. A man to describe, one who is interacting, communicating, loving, judging, questioning, owning, seeking etc., all which has these characteristics use it for his own sake. You must have lots of things (experiences) in order to live accordingly. Your wants must be satisfied so as to satisfy others. Your wills must have meanings that you may be a model to some. Otherwise you’ll be a disaster to all.
I think the author wants to imply that living like a man is only a matter of choice. He can live in any way he wants. By choosing what is good will makes his life better. And choosing what is against will lead to failure.
