I can never get through a man's head who without any plans in life, to live in this world. A man with a goal in mind and heart, to live off in the wild, is beyond my sense of what he is trying to achieve.
We might claim ourselves have an armor of knowledge to survive in this world, but never without plans of achieving our goals. And we might at some point look up to the man's spirit and determination of "you-want-to-do-it-just-go-and-do-it", yet without proper strategies or planning, then you end up being suicidal, that "spirit" is proved plain stupidity and ridiculous.
Even you have the zest, the will and the spirit, it will not get you any farther.
