Never sure

what to write. I can think of things to write -but than retract -never sure what to write. I lead a blessed life. I have problems like everybody does but nothing I need to vent about. My 9 year old van is on it's last tire, my son has a fever, I don't like my job. On the other hand I have a great husband and we have awesome kids. Our parents are in good health and we do have good jobs. My family is the most important to me but there are tons of mommy blogs out there. So what to write?
I am an avid blog reader of several blogs some are very personal some make me laugh some make me angry. All of the blogs I read are interesting to me. I would like to do something different. My life is normal. I want to write something passionate. Open to ideas!
