In my experience in the presentation I've ever done was when I was in school first. When I was in high school. At that time I was making a presenter on the subject of civil engineering and I have become a representative for my team to make the presentation. At the same time I was appointed to head a group to spread. The most important step should I take to prepare the presentation was made, I must prepare myself to deal with people who will see me make a presentation. The second step, I always strengthen the spirit and practice to speak in public because I am afraid, I will make mistakes during the presentation so as not to embarrass myself. the third, I will choose the appropriate clothing for the presentation I would do. The selection of appropriate clothing when performing presentation is very important to always appear in style at the net, so we can say publicly about our own personality. The latter, I will make sure all my work to be completed and tabled it for no more errors in the language used.Valuable experience that I have gained is to say, I was given the recognition that high on the full confidence of my teachers when I finished making the presentation. The teachers are very proud of my presentation because the presentation that I gave very clear and effective way to be understood by the listener.During the presentation of my experience I've ever done, I also never miss a big mistake in its time of my life that I was to step up on stage I fell on the stairs. the incident was embarrassing to me because when the incident I have seen many people who saw the incident. The second mistake, which was a shame that I was mistaken companies are presenting a paper in public. at the time that I had another highly embarrassing incident in my life during my presentation. No person who never pass up a mistake in itself. To me improve my presentation is all I will make early preparation, both mentally and physically so that I would not pass up the mistakes I've ever done before. I will also make a revision in terms of speech and expression me to speak in public. The last one I will make sure the first error is not repeated.
