should
First, we must believe, "Something must change"—not that it should change, not that it could or ought to, but that it absolutely must. So often I hear people say, "This weight should come off," "Procrastinating is a lousy habit," "My relationships should be better." But you know, we can "should" all over ourselves, and our life still won't change! It's only when something becomes a must that we begin the process of truly doing what's necessary to shift the quality of our lives. - Tony Robbins

In rhetoric, a weasel word, is a word or phrase aimed at creating an impression that something specific and meaningful has been said, when in fact only a vague, ambiguous, or irrelevant claim has been communicated.
