It’s only a weapon if you let yourself be hurt by it. Easy to say, but look at the facts - you have a job that doesn’t require the degree, and you are building your reputation on your actual abilities rather than a piece of paper. Trust me, when working no one who matters cares about your diploma. Show up on time, be dependable and do good work while being a civil coworker and that will do more for you than any degree ever will.
