1. Using small scale movements and gestures.
Most rookie presenters are afraid to take up too much space. This hesitance comes across like an apology to the audience.
2. Speaking with low energy.
Actually, this problem is not restricted solely to rookie presenters. 80 – 90% of the presenters that I observe do not expend enough energy. Hence, they come across as uninvolved, uninteresting, and unenthusiastic. Crank up the energy level! You will command more attention and project more confidence and charisma. I cannot stress this strongly enough.
3. Not preparing enough
Granted, many rookie presenters don’t know how to prepare effectively other than preparing their media. Experienced speakers do plenty of research so that they feel confident in their material and their ability to respond to any question the audience might throw at them. They daydream about their topic even during ‘down time’ and often find the most creative ideas when doing other activities. I often come up with great ideas while driving, shopping, or running. It’s important to go through multiple drafts or iterations of your material, revising and editing, to arrive at the most finished form of your talk.
4. Not practicing enough
Not practicing your talks and presentations on your feet is one of the single biggest mistakes you can make. Experienced speakers will often do a dry run of their material with a trusted audience of friends, family, or colleagues. They will simulate the environment of their presentation using a projector and slide remote. They’ll choreograph their movements and gestures which will dramatically increase your ability to remember your material. They recognize areas of challenge (weak segues, awkward media transitions, etc.) and come up with tricks and tactics to help them flow seamlessly through their material.
5. Data centric presentations.
If your talk is focused on data rather than the vivid human story the data tells, you are in trouble.
