Try 7 times. We did. Hubby got it on his 7th try. I didn't get picked but that's okay, at least one of us did.
I'm so excited yet really freaked out too. It's a big deal, not to be taken lightly. At the same time, we've only been selected for further processing, it's not a done deal, we may not get it, so I shouldn't stress myself out about it. Except I can't help it!
