When it comes down to it, public speaking is not an easy skill. Some people are naturally good at it, and others have to work at it. That's why there are specialized courses and groups out there to help people improve their public speaking ability.
When we hear the term "public speaking," we generally think of standing in front of large crowds and giving presentations. However, there are much broader applications for methods typically associated with public speaking. For instance, they can be used while speaking to smaller groups, even during an internal meeting at work. These techniques can also be used in other everyday work situations that are less obvious.
