Obi-Wan Kenobi has been many things, has seen countless possibilities stretching out before him, has nearly started down thousands of paths, has loved a million people, and watched a billion stars go by, but what he has never been (no matter how often he wished it) is insignificant to the galaxy.
He never gets taken to the Jedi and stays as a farmer with a mother who wished for a daughter and a father who cares very little for his family beyond their physical needs, but still the galaxy doesn't leave him alone, because when he crosses paths with a tall young man in the market one day, he allows himself to be dragged along on a world-saving adventure, taking that young man under his wing (because, honestly, he isn't sure how the idiot managed to keep himself alive this long without Obi-Wan's help).
Or he leaves the Jedi Order sometime during his apprenticeship (he had a thousand choices and saw twelve million paths, he just chose something different this time around) and he settles as best he can on one of a hundred planets, right up to the point when someone needs his help (and maybe, it's not the universe who won't leave Obi-Wan alone, but rather his own conscience and need to help that forces him into the center of a galaxy-sized shatterpoint).
