I've been playing guitar for 25 years and I kinda suck. I've forgotten everything I know about music theory, I don't know any songs and my fingers just don't move that fast. But I enjoy coming home and making some noise for 15-20 minutes. I just move my hands around and make a lot of bad sounds until I start making a good sounding riff then I'm done.
That's how I used to play guitar, too. I got a cheapo sound pedal with a bunch of effects and premade back beats. Try to play some songs that I know. Sound bad. Keep doing it until I get bored or it sounds kinda cool once. That's enough for the week.
Am I ever gonna be anywhere close to decent? Nope. Do I care? Nope.
