I don't really have any good answers here. But what I do know is that periodically I have to grab the bull by the horns and spend some time marketing because otherwise what I'm doing will pretty much wither and die.
Well, damn! I thought you were about to drop the secret code for us introverts to open and explore! I must agree, even the thought of being out in public 'selling myself' makes me shiver! Sloth mode is truly activated and I don't intend on moving in that direction at any speed!
I find myself in a similar predicament, most of what I do requires me to be out in front, shouting from the rooftops, I'd much rather be sitting here hiding and hoping my work speaks for itself! Wishing you a prosperous '24! Good luck being a little more extroverted and selling yourself!
