You’re probably familiar with the 80/20 rule— it seems like virtually everything in life can use it in some fashion. Some of the rules invert the two numbers such as 80% of your sales come from 20% of your clients, while others slice two or more things into an 80% chunk and a 20% chunk. In public speaking, the latter rule is used – 80% of your time is spent on preparation while 20% is spent on practice and delivery.
