Hello there,
58 and just started GT last November. Same old story. I played when I was younger, but gave it up for whatever reasons and now trying to get back into it. I'm moving along pretty well. Got some open chords down except that pesky F. A few barre chords and for some reason different strumming patterns don't scare me so I'm pretty comfortable in that department. However, like all of you, I still get hung up on some chord transitions and that just means more practice time. I've gone through Fundamentals 1&2, but I wouldn't say I mastered all the techniques and theory. I play some songs (mostly made easy), but I can't play them flawlessly from start to end without a few flubs. I'm ok with all that. Not going to be performing anytime soon or even at all. This hobby is just for me.
I've also gotten some stuff from Youtube. It can be a good resource but, be forewarned most of the videos give you just enough to get you to subscribe to their channel or paid website. And like GT, unfortunately, printing out or getting a hold of notation is almost impossible so that means follow along with video and hopefully you memorize when the chord changes are coming.
I also enjoy watching some guitar youtube sensations like Paul Davids, Mary Spender and Gabriella Quevedo. Do a search on them especially the latter and you will feel humbled if not more fustrated wondering how somebody so young can be so talented and make it all look so easy. In other words, us old folks got a long way to go.
Which brings me to where I'm at now. Strumming songs is fun, but fingerpicking is where it's at. When you can get your right hand to do more than just go up and down then you've upped your game. So I've started Anders Acoustic Level 1 course and up to his introduction to fingerpicking. Wish me luck.
Like they say everyone learns at their own pace. Don't set too high a goal at first and just enjoy playing what you've learned so far. In three months I feel I've come almost to where I was when I stopped playing back in my twenties. I have enough confidence to walk in to a guitar store and feel like I know what I am doing so much so I bought my first amplifier. It's an Acoustic Brand 15 Watt AV15 model and it is awesome. Such a little amp makes my Ibanez Electric Acoustic sound alive. When the instrument sounds good you want to play it more.
Well anyway that's my update.
Good Luck all.
