In Illuminate: Ignite Change Through Speeches, Stories, Ceremonies, and Symbols, Nancy Duarte introduces how stories, ceremonies and symbols can be used in your speeches to make them puissant. A tip I learnt from a fellow toastmaster to use synonyms lavishly.
On a side note, I have figured why we have synonyms. Words with frequent usage get overloaded with meaning and might steer the mood to a side. I wanted to express an annoying feeling to a magazine and used pesky instead, hoping that it is not used too much making it more neutral than other such words. You can use the Word usage frequency tool to find out if a word has baggage.
Even through Amazon’s ‘Look Inside’ feature of the book, you see how the author has annotated Howard Schultz’s famous ‘bring back my coffee’ speech with the various kind of climb, leap ceremonies used to rally the employees.
