I have an associate who is a big believer in "The Secret" and "The Law of Attraction." I have mentioned before how much I hate the idea that you always get what you focus on.
She said "I don't want to think about [something] because I don't want to attract that into my life."
Suddenly I had a Revelation. I realized something and I almost started dancing, I was so happy.
"Sherry," I said. "The reason that you don't want to dwell on negative things in NOT because of what will happen in the future. The reason you shouldn't focus on the bad is that, when you do that, you ruin your life RIGHT NOW."
I don't think she got it. But I did.
Fear and worry corrupt the present, which is the only time we ever truly have. Isn't that enough reason to try and banish them?
(Because this is the internetz where people tend to pick everything apart, I must disclaim: yes, I know there are legitimate fears and things to be careful of. Etc etc etc).
