It would be one of the more difficult tasks for me to imagine ever being upset at YC for a rejection (Got my 4th tonight, no stranger to it). If this was your first or second, don't worry , it gets better.
I can honestly say I've never felt closer to success and making progress than I do as I, every six months, write up a summary of where I'm at, where I'm going and then compare it with the previous series of rejected applications. Heck next time I could see myself easily with an actual website and customer base, or, if I get lucky, with a co-founder - how novel would that be?
So grow, YC, do it in a way where you don't loose your soul. And hey, if I never get in...well I'm in enough...
I'll make it. That's one of the best feelings. I know that it may look nothing like I presently imagine, but I'll make it. That's the beauty of malleable but relentless dreaming.
Now someone call Hollywood, er Kickstarter, I've got a killer idea for a film about two co-founders in the valley, 'Dotcom Quixote de la Big Chanca' and 'Sancho "the Ramen" Panza' as they go tilting at Heroku Dynos and courting Aldonza Horowitz aka "Andreesenea".
