Your overconfidence and condescension as well overestimation of the value of "time doing x" makes you sound like a prick.
I've seen dudes with the same amount of experience on forklifts cause the most damage out of everyone in a warehouse of hundreds of employees. I've seen dudes in their 60s that have played guitar for nearly 50 years not know jack shit about the instrument and have circles played around them by children.
Experience means next to nothing. It's a useless metric. All that "my opinion is x, and my 31 years of experience makes me right" tells me is that you're more likely than most to have bad habits, bad technique, and pigeonholed preferences.
You know what does mean something? Supporting others on their journey with the instrument instead of talking down at them and acting like you're a part of an elite club that they'll never get into.
With your mindset, you're definitely part of an *exclusive *club. The problem is that you're not gonna find many people out there that care to join you.
