When we meet a person, our first impression is based on their body language and their speech. When someone goes up on a stage, or gives a presentation at a business meeting, many pairs of eyes will be following and judging this person. If you are up there and talking, you want to give your best impression. While many workshops and online videos focus on teaching us how to adjust our body language to appear confident and convince others of our message, less attention is given to how we phrase things. Speech should flow, but there is this one little bad habit most of us have—one that builds a dam in our flowing sentences. This habit makes our message sound as if we are building our foundations on quicksand. Do you know which bad habit I mean? It is the habit of using that not-even-a-word in too many sentences, i.e., the habit of saying "uhm"—something we generally are not even aware of. When we let this habit slip into our speech, it weakens our message, and our audience and clients will be less convinced of our claims. The nasty thing about "uhm" is that it s often too tiny to even notice. It has become part of our expressions and virtually everybody does it. Therefore, it takes practice and effort to unlearn stuffing our sentences with it. To get a hold of your bad habit of using "uhm" , you can try the following exercises: 1)Record your speech when you prepare: 2)Write out your entire speech beforehand: 3)Take a moment to center yourself: and 4)Speak a little more slowly. Make a pledge today: drop the "uhm"!
