La la la, I'm not listening!

Sigh. I'm having a moment. Sometimes it's really hard to bite off small pieces when you just want to bite the whole bull on the bum (just me?). I have a personal training session tomorrow, but I haven't been to the gym this whole week. I'm behind on steps and I'm feeling kind of frustrated. I'm having a serious case of the "buts". I've lost 16 pounds but I still weigh 237. I made a really healthy dinner last night that was delicious but I didn't get the kitchen clean. I made a massive dent in the laundry but  I didn't finish organizing the closet.
Why do human beings do that? Does our culture train us to be this way? Is it nature or nurture? At some point I've just got to stop and say, "You know what? I'm pretty stinking fabulous. Stop being such a Debbie Downer." I'm just going to print off some more endorphin producing images I find on Pinterest and plaster them all over my wall until negative Nancy in my head is so flooded with positivity that it has no choice but to shut the hell up or drop dead. Go me.
