it actually isn't that bad!
for a recent assignment i had to go out and draw people in public - just simple gesture drawings, nothing major. and kept forgetting to bring my earbuds at first. i'd get frustrated, yeah, but not enough to go back in and grab them. so i dealt with the silence, and it actually wasn't that bad at all? i mean, i was going to cafes a lot so that helped, but also libraries? places specifically meant to be quiet? and it was great, to the point where i purposefully left my earbuds at home to finish my assignment today.
consider: going places without your earbuds/headphones on purpose
