Mindless knitting equals trouble

So I'm knitting along last night on the intarsia heart square turned seed stitch heart square completely unknowing that I should be at the point to begin the seed stitch heart. This morning (well over 10 hours later) I realize that I have probably gone past the point and tonight I will probably have to tear out and start again. Well, I guess this square is going to be a challenge from the cast on! Whooo.

Hey, I've got probably over 100 more squares to go...what's the rush?

I've been itching to start something new with what yarn I have. I do have the yarn to make a Sophie bag (a felted cutie purse) but since I've made one, I'm not overly geeked to get that started. I really want to do the Daypack backpack but don't have the yarn!
