A nervous speech

It is a death of time. I am very nervous movement. I think that speech is a very difficult. I tried to practice many times in order not to forget lines and words. When I standed on the desk in front of many people, I cannot remember my lines. I felt my brain was white paper. Therefore, I embarrassed highly. After I finished speech, I regret and feel inconvenience. I have thought how to speech very well. Of course, many practices are useful and necessary task. Most of all, I should change mind into having composure.
