One of my favorite quotes when I hear the ole "kids these days" complaint:
“The children now love luxury; they have bad manners, contempt for authority; they show disrespect for elders and love chatter in place of exercise. Children are now tyrants, not the servants of their households. They no longer rise when elders enter the room. They contradict their parents, chatter before company, gobble up dainties at the table, cross their legs, and tyrannize their teachers.” - Socrates around 400 B.C.
Kids will always be kids. Coach Mayaab at clinic said a few years ago that we have to build relationships and "milk" these kids. Going from playing Fortnite every day to being screamed at in a hot, sweaty, smelly wrestling practice is not enticing to any 14-15 year old kid. Not to mention, we expect them to show up, work hard, and then tell a kid with 10% body fat that he has to lose weight? Those can be difficult conversations if there is not a strong relationship between that coach and wrestler.
Rules without relationships = rebellion. Gone are the days of demanding respect to gain respect from a kid, because they will just find something else to do. But if you show respect to the kid, I feel they will always gravitate towards the thing that gives them attention and love.
