In my next speech I will do my best to keep goodwill, by staying non controversial in the things I say. I plan on saying things that we can all agree on and relate what I say with the rest of the people in this class. I will also do my best to maintain a good mood and a nice smile throughout the entire speech.
I agree really good stuff.
You don't always have to say things everyone agrees with, but it is important to say things kindly to maintain goodwill with the class.
