I waste a lot of time.
Wasted time is a block of time that is not used to do anything productive.
I've actually begun scheduling time to waste.
I read a book. It benefits no one but myself. Except not really. It helps me relax which lets me have more energy for later, it allows me quiet which keeps me calmer, and it helps me feel happy. This leads to less rude comments, less yelling, and more patience.
I watch TV. Probably more then I should, and definitely more then my child should. It offers me a distraction from my problems, gives me a new focus and a way to decompress. This may take away from the time spent folding laundry or filing bills, but it makes me a little more pleasant to be around and provides me non confrontational things to talk about with other people.
Sometimes I even take an extra few minutes in the bathroom. An extra long shower just to be, a few extra minutes to make my hair just how I want it, or put on a little make up just because. It makes me feel pretty and like I'm still just me underneath all the mommy stuff.
I go shopping just to get out and be around people, I bake things I could buy just to make something, and I even take the long way around sometimes when it's sunny and I'm enjoying the drive.
Yes these things all waste time, but if it helps me to be a better me, then maybe it's not wasted at all.
