conditioning

I am a fan of deepak chopra. Something that he says really strikes a chord with me. He says that in our lives, as we grow up we must overcome the conditioning that we recieved as children. Hmmm. Just like a dog of Pavlov. And what conditioning am I forcing on my innocent children.
I see my kids' foreheads furrow and tone of voice deepen angrily and I know that they get that from me.
When I was young, when they were young there was so much innocence and curiosity and joy in us. Is anger conditioning? How do you overcome that? How do you help your children overcome outlooks that you have inflicted upon them?
