Because the client had me roasting on a spit in nearly impossible features Hell for an entire year on a piece of custom software that ate up all the budget and my profitability, I completely forgot about a major other requirement that now will take me months to integrate. And they still haven't paid me for my other work so I can pay my other dev. My vendor/client negotiating "prowess" got me from "still not paid" to "indentured servitude".

FML. How did I convince myself that I'm good at business relationships?Why did I think I would be able to do custom software? I need to stick to just designing websites as a rank and file employee. No, actually I need to disappear until North Korea starts thermonuclear war and nobody cares about software anymore.
