You may not ever be required to perform in a Super Bowl halftime show, but you'll almost certainly be tasked with making presentations at work. For that reason, it's important to hone your public-speaking skills.
"[T]he ability to speak confidently to a large mass of people is a skill to be learnt," writes Ramachandra Bhakta. "It makes a lasting impression and brings you to the notice of several people at once."
If the mere prospect of walking your coworkers through a PowerPoint gives you nightmares, then there are strategies to quell your fear. One research-backed tactic is to reframe your anxiety as excitement, which can make you seem more competent and persuasive.
Another strategy is to be well prepared and practice, practice, practice. Practice at home in front of a mirror, by a window and/or practice in front of a friend or relative. With more preparation, the jitters will diminish. Also, have your presentation completely written in large print with a few areas in bold print for easy referral during your presentation.
