...regarding public speaking?
Your audience wants you to succeed.
While most professional meetings do not require a 2 drink minimum (although sometimes we wish they would), remember, it's equally as painful to watch someone tank as it is to tank (well, in most cases anyway). Great information delivered with a shaky voice loses its greatness--we are focused on the delivery and not the information.
Pull your audience in! Engage them! Don't just read to them directly from your Powerpoint. Not only is it boring (and frankly, insulting), but it's a waste of time as the handouts could have easily been printed and mailed.
From a young age, we learn that when it was time to be read to, it was time to grab a blankie and lights out! Not exactly the climate you want to create for your fabulous speech!
