I haven’t played in 7 years, and I just recently started back up. I know how you feel. I just had to walk myself through Twinkle Twinkle Little Star the other day, like I was back in 6th grade. Consistent practice is key in learning and mastering a craft. Don’t give up, and more importantly, DON’T compare yourself or your progress to anyone else. You can rock this. I have faith in you!
