Welcome to TreeWorld Urbantreemanagement!!!
I may have misunderstood, but is YoungBull your son?
I'm a rather headstrong young man in my young twenties as well, the only advice I can give is: make sure he uses two tie in points. Eventually he'll learn that he's fallible through his own mistakes, but it may take some time. In the meantime, as long as he's using propper equipment and techniques it should get him through his initial learning phase.
Us youngin's can be difficult to teach since, well, we know everything of course!!! I told my dad the other day; the older I get, the smarter I realize he is
Just stick with him and hopefully his learning curve will increase proportionally along with his safety.
