It’s a great article on something that’s useful, but a bit overconfident in its universality. Better at what? There are many dimensions to being a guitar player. Is it technique? Theory? Ability to pickup a song by ear (this article)? Better at playing in a group? Better at playing solo? Better at reading music? Better at accurate bends? Better at fingerpicking?

One of the nice things about music is you can’t get good at ALL of it. You have to pick where to focus. I’ll also say, you might need to ask yourself if you want to get better. I love relaxing by reading through the chords on a new song and playing it. I already have a job, and the time I truly have for intentional practice is like once a month. Most people are not studying to become guitar pros but to enjoy their time with the instrument. If that is your goal let joy be your guide. Perhaps some short term pain is part of that journey but really weigh out what you want out of the experience.
