presentations

I feel that presentations are very important. There are many reasons why we should practice this now, because who knows how many times we will be faced with having to not only present something but speak in front of others. I also feel in everyday life we are required to talk with others and it might not be a presentation but it is speaking in front of others. I myself do not mind talking in front of other but I just like to know what I am talking about. It can look very bad when speaking on a topic that you have no knowledge about and your audience CAN tell when you do not know what you are speaking about.
