Well question sir when we are doing first time presentation on the 1000 of people sitting in front of you then we surely have a fear in our body. So for that we have to go with different stages and we should properly give a speech so everyone can listen it.

When you are doing presentation first of all be prepare about your topic and go on dip thinking about your presentation because people sitting on front of you will ask a question so don't be fooled that they will not ask question instead of that we should go dip thinking so you can able to give answer of his question.

Second step remove the fear from our body so you can able to speak or explain your presentation very smoothly without any doubt and no one can stop you when you are giving speech with melodious sound.

While giving presentation we should laugh the people who are sitting on the chair and listen our presentation so they cannot become a boring.

Always have a smile while driving a speech so everyone has a good face on you and also don't you loud voice because people who are listening cannot become afraid of your noise.
