A habit is a way of thinking, feeling or behaving which tends to occur unconsciously and often. Speaking in public comes along with several bad habits. Clenching your hands, pacing the flood, avoiding eye contact and speaking too fast are things listeners would read as signs of being nervous and insecure.
Speakers frequently fall into the bad habit of giving generic presentations that are not tailored to address the needs of this particular audience. Listeners know when the speaker has not done their homework, and their response ranges from disappointment and frustration to anger and disengaging.
From professionals to beginners, many public speakers fail to engage in eye contact. A lack of eye contact implies insincerity, disinterest, detachment, and arrogance. Clenching or wringing your hands, pacing back and forth, keeping your hands in pockets, jingling change or keys, twisting your ring, gripping the lectern, licking your lips, adjusting your hair or clothing, fidgeting with a pen, bobbing your head, placing your arms behind your back, and touching your face are all mannerisms that need to get the boot.
Most veteran speakers prepare. They make sure to know their content and organize their topics. Preform your entire presentation aloud first and the opening and closing a couple more times. To avoid putting your audience to sleep, make sure to keep them engaged and crank up the energy. Speak expressively, smile sincerely and savor the moment.
