so am i a stupid samaritan or what??
I don't think so. It's always constructive to affirm constructive statements in the mind or otherwise, regardless if they are intended directly to "you" or not. Whatever we affirm will be implanted in our consciousness, and will create opinions and beliefs. These will eventually outplay themselves in our life one way or the other, depending on how strong and consistent our application of affirming them has been. So, we need to watch out also that we don't get into the habit of affirming what we don't want to manifest, because it will work that way as well.
