Planning Is Critical

i'm always trying to have a back up in case the original plan doesn't work. I had a situation a while ago where i was giving a presentation, and right in the middle of the presentation, the electricity went out. The critical part is that you're still able to speak to them. You can let the power point go. A lot of these maxims overlap in the ideas they seek to convey. They try and attack hem from different angles so that people can internalize them better.
