It's a hard email to swallow, but I'm going to continue my work. I was excited at the idea to be a part of Y-Combinator; it's tough to entertain the idea of pursuing your product with the support of peers and successful people. Then realize you're not going to have a chance to WOW Y-Combinator at the interviews in November, nor will you be there in January to love the three months. I know my idea is great and I can make it happen, call me if you want to join in - you have my number.
