Thinking isn’t just for off platform.
While it is true we never want to ‘wing it’ in place of solid preparation, it is also true that we often need to allow ourselves to think and adapt. People like to see us think, so don’t be afraid to respond to a good question with a pause, some solid thought and then a casual answer.
As advanced speakers we are able to think ‘on the fly’ and offer interactive presentations rather than canned speeches.
