As I get older it gets much much harder to feel stupid at something new when you know what it feels like to be very good at something else. This I feel is the key reason people stop picking up new skills, it feels miserable to be back at a beginner level and so much more satisfying to do something you’re proficient at.
However, if you can recognize this and reset your expectations then you will probably find you have extensive general skills to bring to bear around learning and self discipline. Those skills will make the actual learning process overall much quicker compared to learning your first few major skills, it just might not feel like it.
