Taking up any musical instrument is a permanent learning journey, there’s always something new to take on board, be it a scale, chord, technique , whatever. However, as Dad says, it should be enjoyable. When I first picked up the guitar as a youngster, I was taught some chords and I had a book or two, but what I did most of all was learn tunes that I liked and wanted to play and I didn’t get too bogged down with scales and theory. This may not have been the wisest course with regard to musical proficiency but, 50 years on, I’m still playing and playing tunes that give me pleasure, not what some book, course or latest internet craze tells me to. What makes you smile, when you’re playing? Do that more and the other things you want to learn, but give you trouble at the moment, will become easier. You may not ever perfect everything to your personal standards (who does?), but you will perfect some things and that’s not bad.
