Ok. I'll play along.
Origin story incoming:
Id haul cargo within the inner planets for the republic. Not by choice but that's where I'd be born. On a routine delivery to an outer planet outpost, I'd discover my destination decimated and find a lightsaber from a long gone Jedi. Sure I'd be good with a blaster, what person who grew up on some backwoods planet only to become an intergalactic trucker wouldn't? Something about this lightsaber triggers off new feelings. That's how I'd learn that I'm force sensitive.
Can't trust the sith and Jedi are contradictions of themselves. Sorry peace keeper warriors, but search your feelings... You know I'm right. I would not receive any formal training and spend the rest of my days as a space pirate, looting the inner edge of the outer rim to avoid the crazy powerful sith or the over zealous Jedi trying to become a hero. Over time my legend would grow and the story of the space pirate Captain Fleabeard would become one of romance and wealth.
