Most of the men important in my early life followed these rules. When I was of age, I promised to do my duty to God and country, obey the scout law, help others, and keep fit, exercise my mind, and live a moral life. Further pledged to be trustworthy, loyal, helpful, frieldly, courteous, kind, obedient, cheerful, thrifty, brave, clean and reverent. I still follow that path to this day (though not always as successfully as I'd like) and gave my son the same opportunity. It's a shame that in todays society being a "gentleman" is seen as either a reactionary zealot or a comical anachronism.
My 2 cents.
