Two words...Inner Game. Seriously.
Not to rehash what Kupid said, but I'd like to quote my first Drill Sergeant.
Quote:
"Don't be afraid of failure. You failed, it means you tried. Hooah?"
--DS Johnson
Second thing is, learn from failure. I feel like it's a quote from somewhere, but I can't remember, the gist of it being. "Success teaches us nothing. It is only from failure that we learn."
In my opinion, you're already on the right track, in that you didn't blame them. It may sound cruel, and apologize if that's the way you take it, but for the most part, when a set backfires like that, it's your fault. Don't let that be a bad thing. I'm a big believer in recognizing ones weakness and faults, of which I am in no short supply. But I recognize them, so that means I can do something about it. It's when you're like a buddy of mine, though I love him like a brother, and you think that the reason you can't get women is because of them, or because of who you are and that you can't change, that you really start to stagnant.
The key here, is self awareness, and perserverance. Realize, "Hmm, came in at the wrong angle. Clearly made it look like I was trying to pick them up." And, adjust fire, in artillery parlance. I believe it's referred to as calibration in PU terms. It's a learning experience.
One of the first sets I tried to open, before discovering Game, I got blown out horribly, and even then (I have recently upped my self awareness level ten fold) I shrugged it off, and blamed myself for coming on too strong.
One caveat, though, don't make the opposite mistake of not going for it because you want to learn from a failure. I did that recently and am STILL kicking myself for it.

Here's to the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to tell the difference between the two.
