If rejection makes you stop building the company that you envision, love, and put all of your effort behind, then you will never succeed running a startup. This may be a bold statement, but I'd love to hear what Jobs, Gates, Zuck, or anyone else with expertise in the area have to say.
I definitely agree with this.
If you applied to YC to have your project validated by @pg and associates. Then you should think twice about your real motivations.
Only close shop when you're sure your idea is not a good one or that you KNOW that you're not able to achieve it.
