Each song has its own secret that's different from another song, and each has its own life. Sometimes it has to be teased out, whereas other times it might come fast. There are no laws about songwriting or producing. It depends on what you're doing, not just who you're doing.
I even played bass for a while. Besides playing electric guitar, I'd also get asked to play some acoustic stuff. But, since I didn't have an acoustic guitar at the time, I used to borrow one from a friend so I could play folk joints.
There happened to be guitar classes at the college, and there was a guitar teacher there with whom I used to play. In addition, I also would go out into country schools and teach little kids basic guitar and singing a few times a week.
