Do you like presenting/speaking here is what it takes.
Some people are worried or scared to present or speak in front of large groups. One great great speaker was Abraham Lincoln. He spoke to large crowds all the time. He also wasn't afraid to say what he felt. Other great speakers included Martin Luther King Jr. All you really have to do to present is talk about a certain subject. Posture is key don't be slouching also speak clearly and loud enough that people can hear you and not have to strain their ears to hear. That is what I believe it takes to present to people or one person
