Nice find, Pete. Thanks.
I can especially relate to reason 3 (Not Having Fun With Guitar Practice). I wish the author had explained that it is almost impossible to have fun with guitar PRACTICE. Let's face it, practice is boring, but PLAYING is fun. If you can work your practice in by playing, practice can BECOME fun.
For example: Want to learn a minor pentatonic scale? Then go find a song THAT YOU LIKE where the guitarist is rolling all over a minor pentatonic scale during a solo and learn to play it note for note at tempo. While you're at it, learn the why as well as the how. When you're done, if you've done it right, then you'll have mastered the scale as well as having learned a song that you like.
By the way, I'm not good at practicing what I preach here. I think I know what needs to be done but not necessarily how to do it. ("Those who can't do, teach?") I appease myself in the knowledge that even Nolan Ryan had a pitching coach and Mariah Carey has a voice coach, neither of whom are as "good" as their students, but can help them improve nonetheless. I sometimes think that I would make a very good guitar teacher because I could teach my students how to avoid the bad habits that I have acquired over the years. ("Don't do as I do, do as I say." )
Maybe I need to write my own article.
