I want to deliver a Speech in front of Public.

I have to do speech in public speech class tomorrow. Fortunately, this speech will not be long than before last speech. It just spends two minutes, so I feel rather easy and nervous. However, it is difficult for me to choose in terms of topic on speech. The topic of speech is concerned about the speech of tribute. That is, I should pay a tribute person, on a group, or events by chosing one among three items. First of all, I chose the person. Then, I have been pondering which choose person as honoree last night. At last, I decided to choose Bill Gates. I am nearly finishing the speech now, but it seems not to be organized well. Therefore, I will complete the address after eating dinner. I would like to pray for God in order to do well speech tomorrow.
