Are your speeches like Hospital Pudding?
Speaking well should be a part of a business plan, as a part of supply chain for ideas. Speaking in a town hall is the essence of managing the water cooler conversations for the next two weeks.
The only reason people don't walk out on some speakers is the same reason that you eat pudding in a hospital. You eat pudding because it's the only thing in front of you. Given better options, that pudding would be in the garbage.
