1.Smile
Smiling increases endorphins, replacing anxiety with calm and making you feel good about your presentation. Smiling also exhibits confidence and enthusiasm to the crowd. And this tip works even if you're doing a webinar and people can't see you.
Just don't overdo it – no one enjoys the maniacal clown look.
2.Practice!
Naturally, you'll want to rehearse your presentation multiple times. While it can be difficult for those with packed schedules to spare time to practice, it's essential if you want to deliver a rousing presentation. I’m famous around the office for staying up late the night before a big presentation, practicing over and over. If you really want to sound great, write out your speech rather than taking chances winging it – if you get nervous about speaking, a script is your best friend.
Try to practice where you'll be delivering your talk. Some acting strategists suggest rehearsing lines in various positions – standing up, sitting down, with arms open wide, on one leg, while sitting on the toilet, etc. (OK, that last one may be optional.) The more you mix up your position and setting, the more comfortable you'll feel with your speech. Do a practice run for a friend or colleague, or try recording your presentation and playing it back to evaluate which areas need work. Listening to recordings of your past talks can clue you in to bad habits you may be unaware of, as well as inspiring the age-old question: "Is that what I really sound like?"
3.Transform Nervous Energy Into Enthusiasm
It may sound strange, but I'll often down an energy drink and blast hip-hop music in my earphones before presenting. Why? It pumps me up and helps me turn jitters into focused enthusiasm. Studies have shown that an enthusiastic speech can win out over an eloquent one, and since I'm not exactly the Winston Churchill of presenters, I make sure that I'm as enthusiastic and energetic as possible before going on stage. Of course, individuals respond differently to caffeine overload, so know your own body before guzzling those monster energy drinks.
4.Adjust to Your Surroundings
The more adjusted to your environment you are, the more comfortable you'll feel. Make sure to spend some in the room where you will be delivering your presentation. If possible, practice with the microphone and lighting, make sure you understand the seating and be aware of any distractions potentially posed by the venue (e.g., a noisy road outside).
5.Admit You Don’t Have All the Answers
Very few presenters are willing to publicly concede that they don’t actually know everything because they feel it undermines their authority. However, since we all know that nobody can ever know everything about a given topic, admitting so in a presentation can actually improve your credibility.
