I am an electrical engineer by training, a programmer by necessity, and a teacher when I can. I've been a marketer, a publisher, and a retail manager. I've worked for companies ranging from mom-and-pop less-than-10-people up through Fortune 500. What have I learned from this? Well... to be patient. Very, very, patient.
I still periodically participate here on Stack Exchange, but you'll find me more often over on Codidact.
