You have heard a lot of quality advice here, and virtually none of it points in the direction of, "go ahead and quit, man". Everyone has encouraged you to keep at it, and to keep playing. I'll add this much; * It's helpful to take a break every now and then. Giving the guitar a rest for a week is healthy. When you come back to it you often find yourself refreshed. and, * Not being in a band, you currently suffer from a lack of a specific motivation. I believe in performance goal-oriented practice, and I always will. In other words, if you don't have any idea where you're going, how do you know you're on the right road? 1. Arrange to set-up and play at some public venue. A street corner, or the plaza of an outdoor shopping mall. And then get out there with your pre-recorded back tracks, and play for people walking by. Leave your guitar case open with a few dollars and some coins as seed money. Let people hear you play. Be a busker in other words. You would have a specific performance goal of getting a ten-song set list together. You would now have something for which you must prepare, and that is playing live before passersby. 2. Call around to some old folks homes or assisted living facilities. Talk to the Events Coordinator. See if they regularly have guitar players come in and play and sing for the oldsters. Set up to go in an play for an hour. Work up some great oldies that you can play and sing for them. The old ladies and men (mostly old ladies, because men don't live as long) will love it, and they will sing along. This is another specific performance goal that would force you to prepare in a specific manner. You'll need a music stand for your lyrics and chords, most likely. and, 3. Advertise on Craigslist or the local guitar store bulletin board for somebody to jam with. That's right. Offer yourself up to jam and perform with perfect strangers. Chances are there are other fellows who need to break out of a rut, and who want to sit down and play guitar with another player. Arrange to meet in a place where you can play with adequate social distance. When you play with other guitarists, you will always find something they have to offer or teach you. And you will find some things that you can offer them. Tips, tricks, riffs. In the end, you will both get better, and you will have a hell of a good time. It's like signing onto the 'ladder' of local tennis players. When you play with worse players, you enjoy being better than somebody else, but your competition helps them to get better. And when you get on the court with a superior tennis player, their skills force you to step up your game, and you get better. Okay, I'm gonna shut up now.
