Good work. We were invited for an interview, but I can tell you that I've failed to get an opportunity so many times in my life that I've lost count. I've had a handful of wins, but have thrown the dice tens of thousands of times. Opportunity is a fickle beast. There have been dark dark days (and months). My ego and pride is covered with calluses. It's depressing and it makes your humble, but it's not a sign of defeat. Push through if only because the alternative is to concede defeat.

A couple of my biggest regrets are not applying to Google in 2000 when I was graduating from CPSC: "Search engine? Well that sounds boring. And they don't even have a business model!".. Opps....

The other was not applying to YC in November 2009. "Oh the next class is too far away." I had a killer prototype, and since then the whatifs always haunted me.

Better to try, and be overlooked, than to never try at all.

Same. And I can think of a couple of reasons why I might have been rejected, which means I now have an area to focus on to develop the company (and the idea) further.
