All war must be just the killing of strangers against whom you feel no personal animosity; strangers whom, in other circumstances, you would help if you found them in trouble, and who would help you if you needed it.
Clothes make the man. Naked people have little or no influence on society. You cannot depend on your eyes when your imagination is out of focus. As in the words of Wayne Dyer, when you change the way you look at things, the things you look at change. Sometimes to know with certainty that a particular thing is "true", will actually be the very thing that keeps you from attaining the things you seek to achieve.
The mind that becomes soiled in youth can never again be washed clean. I know this by my own experience, & to this day I cherish an unappeased bitterness against the unfaithful guardians of my young life, who not only permitted but compelled me to read an unexpurgated Bible through before I was 15 years old. None can do that and ever draw a clean sweet breath again on this side of the grave.
Nevertheless we have this curious spectacle: daily the trained parrot in the pulpit gravely delivers himself of these ironies, which he has acquired at second-hand and adopted without examination, to a trained congregation which accepts them without examination, and neither the speaker nor the hearer laughs at himself.

Always obey your parents. When they are present. This is the best policy in the long run. Because if you don't, they will make you. Most parents think they know better than you do, and you can generally make more by humoring that superstition than you can by acting on your own better judgment.
