Everything is basic and fundamental. Sophistication's are meaningless. Luck is a major factor in life. Artillery shells and other enemy fire kill at random. Surviving is as much luck as it is anything else.

Men's lives are dice in combat and when god throws them he frequently throws snake eyes. I wouldn't wish combat on anyone but the experience will carry you for the rest of your life. As a director of major corporations both domestic and foreign I saw and witnessed every form of behavior known to man and some new ones. I knew thieving Chief Executive Officers, lying and crooked lawyers, dishonest executives, incompetent directors, self serving directors, lying advisors and dishonest accountants. I saw people refuse to stand up and fight and who had no principals of any kind.
