Positive Thinking

I ran across a news video about the power of positive thinking in the outcome of cancer treatment. Here is the linkJust how powerful is positive thinking?
It made some very interesting points. There are two distinct schools of thought on this subject. There have been studies that show that positive attitude has no effect on cancer outcome. For every person who says that their positive outlook contributed to their cancer cure, there are many who died and carried that positive attitude to the grave.
I have been culturing my own positive attitude as I make my way through the maze of cancer treatment.  When I make a statement that implies that I am not seeing my cancer as 'cured' I am reminded by my friends or family that I need to change that thought to, 'my cancer is cured'. I just realized that this puts tremendous pressure on me. It tells me that if things don't go well it is somehow my fault because I didn't think 'positively' about my situation.  Here and now Im giving myself permission to think and express all of my thoughts whether positive or negative. No more mind games. Im feeling very optimistic at the moment. I plan to go with that as much as possible. Regardless of whether this attitude has an effect on the outcome of my treatment, I feel that my life will be richer than if I had a 'woe is me' attitude.
It's all about the life you choose to live. No one knows when they are going to die. To me, the best plan is to squeeze every ounce of joy out of every minute of every day. I don't want to miss a thing!
