I'm 67 and been playing about 10 years. My instructor said that starting to play as an adult has to reset my expectations, especially when you see a teenager shredding a song on you tube.
I love learning songs and playing along with them. I have no expectations to play in a band except maybe when I turn 80 and then I'll call it:
"The Octengenariens"

Bottom line is just enjoy the learning and playing.
