I had to give up last year for a couple of reasons - I developed tennis elbow from playing concertina so had to rest it. Then life got busy - moving house, my job etc, and some health issues where I was too tired and had low energy. If you're focusing on keeping your job, and day to day stuff, it's easy for music to be pushed aside. Now finally I am picking up the concertina. Discovering of course that I have forgotten a ton of chords I'd learned and whatever progress I'd made last year - well it felt like 3 steps forward then 2 steps backwards. I know I have to be patient, and have short but regular practice sessions and do my elbow exercises as preventive measure. Playing with others is key for me to keep going and keep motivated. Otherwise I run out of steam quickly and get distracted by other stuff going on in my life. I wish I was a more serious musician, but by nature I'm a dilettante, flitting from one shiney thing to the next shiney thing. I finally have learned not to take on NEW shiney things and just bounce back and forth between a few shiney things. That way, I see some slow improvement, although never as much as a dedicated serious musician.
