Most people never think about their attitudes at all. For most of them, it’s a matter of beginning each day in neutral. Their attitudes are neither good nor bad; they are poised to react to whatever stimuli they encounter. If the stimulus is good, they will reflect it; if it’s bad, they will reflect that, too. They are chameleons, going through their days reacting to whatever confronts them. And these are the people of our environment. That’s why it’s so important for us to control our attitudes, to make sure they’re excellent or good.
