Believe it or not, I used to play classical guitar. I gave it up about 30+ years ago. That’s a long time to put something down and take it up again.
Why did i do it? Well, classical guitar is a lonely road, since you’re playing by yourself. It requires hours of practice, and at least for me, it seemed to take a lot of energy for very little reward. I had other priorities in life, like raising a family, finding/doing a job that was tolerable that would allow me to retire, etc. These were more rewarding.
Now that I’m retired, I have more time on my hands, and I can start from scratch and re-learn some basics, and put just as much effort into it as I want. I can go into rock, folk, blues, jazz, whatever I want. I remember most of the basic chords, but the old hands and fingers need lots of work to sound halfway decent.
