Will it increase your likelihood of success? No. There has yet ever been a startup that has developed after a rejection from YC. Will moving to SF help you? No. There's a lot more action in the east coast for tech then there are out here. In fact, I would say you're going to have a much harder time trying to figure yourself, your startup, and navigate the social culture and scene. Your budget is also naively out of whack.
But you're going to enjoy your adventure, good or bad. I applaud that, I applaud that simple affirmations.
Good luck, let's grab lunch when you're out here.
