It’s an oldie but a goodie. Don’t sell the sausage, sell the sizzle!
Coke would never sell based on the taste. Coke sells on the feeling you get when you drink it. The feeling of refreshment of spending time with friends, of good times.
Even if your speech has the most amazing content, if you don’t perform that speech, you will not change the way your audience sees, thinks, acts or feels after hearing you deliver it.
Performing your speech means pausing, it means using silence, it means changing your pace, adding light and shade, standing in one spot for one point, and in another to deliver something different.
It’s maybe getting angry, getting sad, being funny and maybe, being mad.
A great speech must show true emotion and that is why you must perform, every you step up to speak.
