Bill makes a very good point when he says:

"It would be good to sort out what you want to accomplish and works towards that. This, at our age, should be for enjoyment only."

Here's the hard cold truth about why it's so fricking difficult for us Boomers to learn new guitar skills

Kevin, I don't want to be a dick, but I have a bit of OCD and I keep ruminating about a word you used: "demotivating"

Everyone who reads that part of your post knows exactly what you mean, but it's unfortunately still not a word registered in the English language. Proper English dictates that you use a word like "discouraging", an antonym for "motivating". But the word "discouraging" really doesn't capture the essence of what you meant when you said "demotivating", does it? It's a great bit of slang and, in my opinion, should be formally adopted by Webster.

"Discouraging" refers to something that temporarily makes a person want to stop what they are doing, while "demotivating" (as I interpret it) refers to something much more enduring; something that weighs on one's soul to the point of nearly crushing it altogether.
