I think there's nothing wrong with it as long as you're truly happy and it's where you really want to be, as seems to be your case! In that situation, I'm happy you reached that conclusion :) This was more thinking about the people who obviously, honestly aren't happy but feel this is just the way things must be, that they stay in a place as dictated by...I dunno, fate? or fear, often.
You're right, the search for the perfect spot is a slippery slope, since there always will be more to find out there. But the search for the pretty-darn-near-perfect place sounds worthwhile to me :)
