I dont get how can knowing to play a musical instrument be way more common than knowing how to draw.
Every children will have access to pen and paper, everyone knows how a pencil works.
Now to play an instrument, theres so many complexities involved, and its so not intuitive to convert what you hear to figuring out how to reproduce on the instrument.
Now if you fart on a corner, 60% of the ppl who will smell it will know how to play an instrument, and 2% know how to draw. At least on my personal experience is how I perceive.
How can that be?
I think it's because drawing is hard and a lot of people get discouraged by the poor results they start with, whereas you can get something decent out of an instrument pretty fast.
Usually I just find a nice place to pace around in-doors (little foyer/hallway area), and pace for an hour or two (or sometimes alot more), letting my mind wander over a vast range of things - game mechanics, world design, fictional lore, past movies I've watched, my hopes for the future of the business I'm trying to start, and things like that. Sometimes I pace for just 5-10 minutes, a dozen times in the day, and sometimes I pace for hours-straight. It really confuses house-guests and visitors.
I'd do this more often if I had the focus for it. My mind just wanders to irrelevant things too fast. I have trouble focusing on something unless I'm in front of my computer dealing with the issue, which is annoying because then I have to always be in front of my computer when I want to overcome a problem.
