making ppt and presentation

the boss said:

1. less words, not filled in the whole page
2. larger figures, esp. the words in the figure
3. the title and conclusion will connected to each other.
4. the items in the conclusion will be explained and emphasized during the presentation, and shown in ppt.
5. every single diagram or statement in ppt must be meaningful, otherwise it is redundant.
6. speak lower to give enough time for the audience to listen clearly and understand well.
