Try to find humor in the situation if things do not go as planned. There are many variables when you speak in public, which means that there are many opportunities for things to go wrong. The microphone or projector may not work, there may be an interruption in power or someone may enter the room in the midst of your speech. Try to take tort
in stride. Taking things too seriously can result in you having a meltdown, so try to laugh off any issues that may arise.
