So what I do when, like today, I don't feel like working, is that I start working anyway and I pay attention to what signals my brain and body is sending me.
Then, after working a while, if I honestly do start to feel worse I will stop and quit. However, if I just feel a little bit crummy as I do now I keep on plugging along.
As someone once said, "Most of the world's work is done by people who didn't feel much like getting out of bed. By the way, I am having coffee and V-8 Juice. I am a big fan of V It's cheap, it only has 36 calories, and, when you pour it over a tall glass of ice cubes it really tastes great. Give it a try. It's a nice alternative once in a while to eating or having a soft drink. Now, back to marketing. You know, one of the remarks I hear all the time when I ask someone what they think of one of my ads goes something like this: "Oh, I'm not a good person to ask.
I never buy anything by mail. Mail order sales run into the billions of dollars each year but rarely will you run into anyone who admits to being a mail order buyer. Personally, I think all these non-mail order buyers are the same people who don't read the "National Enquirer. Once again, it must be all those Martian invaders. What I am doing here is redundantly making a point and I am going to be even more redundant. Here's another little glimpse into one of the vagaries of human behavior: Once I asked at class at USC how many of them preferred to go to plays more than movies.
I then asked to see the hands of people who had seen a movie in the last week or so. Bond, this phenomena is common. All of us, including thee and me, have a slightly shrewd idea of ourselves. We often try to convince others and ourselves that we are something we are not, something we have an idea we "should" be.
Therefore, truth, my good son, can be determined NOT by how people use their mouth but rather how they use their wallet. I want to burn this message into your mind. Be skeptical of what people say. Be skeptical of surveys. Of questionnaires. Hach Company. Orion Research Incorporated. The calibration graph for the Orion residual chlorine method must be derived using a reagent blank and three standard solutions, containing 0.
