No, I think what it is is my changed perspective. I have talked about perspective in this post: It's All About Perspective :http://babywisemom.blogspot.com/2008/05/its-all-about-perspective.html. I have shared in the past about a tantrum from one of my girls not phasing me like it did Brayden. With Brayden, I thought my sweet child was gone forever. With my girls, I understood tantrums were a normal part of life and didn't let it phase me.
So my experiences have taught me to have the proper perspective, and with the proper perspective, I can have a positive attitude about life. A positive attitude is really a powerful thing. Psychologist and philosopher William James wrote, "The greatest revolution of our generation is the discovery that human beings, by changing the inner attitudes of their minds, can change the outer aspect of their minds" (A Toolbox for Humanity page 127--quoted in Living the Abundant Life).
We get to choose our attitude each day. Yes, circumstances can make that harder or to do, but despite what is going on around us, we can choose to look on the positive side and have a positive outlook in our situations.
We can't control the wind, but we can adjust our sails. How true it is. All the grumbling in the world about the direction, force, or temperature of the wind won't get us anywhere, but adjusting our sails to work with the wind will get us to where we want to go.
