Hi Pardisi and welcome!
I'm 36 (shhh! don't tell anyone!

) and although I don't have children, I can relate to the fighting about stupid things with my husband. The also changing contradictions.
It's great that you have that desire to change. It's going to be one of the hardest things you'll ever work for. But it's worth it. And these a great group of folks on this board to bounce ideas off. Hope we see more of you.
