I think, like Sonita, I feel lazier when I'm not fixed up. Not everyone feels that way, obviously, but it's what I've been struggling with lately. Also, like others mentioned, I want to get fixed up for my dh, not just when I'll be seeing folks outside the house. I have even begun to worry about my kids seeing me not taking care of myself. I don't want to look like a mess to the all the time. I may not look in the mirror until noon, but they've been looking at me all morning, and I'd like what they're looking at to be not too scary!
But that's just me. I totally understand about the more relaxed approach. One of the things I changed since posting this, was to change the time of my shower. Rather than showering right before bed, I now shower earlier in the evening. Then by bedtime, my hair is almost dry and it's not a wild mess in the morning.
