Keep learning! The guitar sounds like fun. I worked on the piano for awhile. I taught myself Fur Elise and the Entertainer. It took a bit of effort to get my left and right hands to work independently. But you have to keep at it or it tends to slip away and I had too many other interests.

I was wondering what you put up on Etsy. I put up a couple of spreadsheets recently just to see if there was any interest. None so far. I think you have to do a lot of promotion on Etsy and I'm not a promoter. In fact I think I hate marketing.
