Look good always....or sometimes?

I was thinking this morning how rare it is that I put effort into my appearance, such as make-up and "done" hair. I know that there are a lot of women out there who won't leave the house without being completely done up. I just don't feel I have the time, most mornings. I shower while the kids are still sleeping and then get dressed and get them up. I come back to me while they are eating breakfast and take the towel off my hair and do as much as I feel like with it. Normally not much. Back to the kids and getting them dressed and we are all out the door.
I am thinking I like my way better. My reasoning is as follows. If you dress up every day and always wear make-up and always do your hair nice, people stop noticing. They then notice if you do nothing and have a "natural" day and then think you look like crap or something is wrong. Me, I am "natural" most days and people tend to notice me and pay me compliments on the days that I put effort in (at least 2 work days a week).
My point is, I would rather be noticed for looking good than looking like crap.
