It doesn't sound like YC is something that you wake up on Monday and say, "I'm going to live in California for 3 months on savings without a reliable source of income and hope I can turn my idea into a business."
Any ideas which?
From what I've learned talking to YC startups and reading about others it seems pretty mixed, that some spent many hours planning and some made the decision at the last minute.
> And it was, without a doubt, one of the best experiences of my life.
Out of context this wording is kind of funny/sad.
