I do not think it is selfish to take time to help yourself. I tend to believe it is one of the many very wrong things women (I do believe it is mostly women, but certainly it can happen to men also) are taught by society and family. Taking care of yourself is not a selfish act. Taking time,(daily) or even a few hours a day once or twice a week to accomplish this (assuming your children are clothed, fed, and not left out in the snow) is not a bad or selfish thing. In the big picture it is a good thing for you and your family (if family is a concern) - a more balanced you is better for them.
