I'll reiterate something YC partners have said. If you're working on a startup, even if you don't apply, completing the application is a great way to clarify your idea and focus on what's important moving forward.

If you don't have much to show yet, don't sweat it. Just get started, and work on your ideas with whatever time you can afford. Some applicants will have accomplished more, but some may have started with huge disadvantages and overcame far more adversity to achieve a much less impressive track record. Regardless of not being the type that seemingly has an advantage, if you're going to build a successful startup, then go build it.

I just returned from meeting with the CEO of the only YC company based in my state. He's an awesome guy, and I'm very grateful he took the time to meet with me and offer his advice. Throughout the meeting, it seemed like he had the impression that I had no idea how much work I had ahead of me and how hard it actually is to get into YC. Being underestimated like that is so thrilling; I love it! It means he'll be that much more impressed when I accomplish what I plan to do whether I get into YC or not.
