Ways we strengthen our minds and bodies and what to avoid.
I'm sure there are many others we could add to the list that would build wisdom, strength and character in young people.
If you view it as insurmountable then you've failed before you tried. Perhaps I have an advantage of age because I remember a time when people did respect each other. It's the way we were brought up. There were always contentious elements wanting to break the rules but mostly kids were raised to respect their elders and to respect authority of your parents and those of others. You respected teachers, police, religious figures, service people, not because of who they were but what they represented. In school we said the Pledge of Allegiance, we stood for a moment of silent prayer, we dressed according to a dress code. Yes sir, yes ma'am, please and thank you were instilled in us. Men opened doors for women, we seated the women before we took our seats. Why? Because our parent taught us to do so.
Society was more civil, respectful and polite. We have a road map we can follow if these things start in the home. I know it sounds impossible but that's only because we've lost our collective memory of how much better we functioned when we gave and received respect and learned that at an early age. It's now rare, but when you meet a respectful and polite young person today you are left with a good impression and the knowledge that good parents still exist.
