When I was younger I had to do a presentation at a school in Washington DC to get a contract. I was in a coffee shop and there was a huge guy next to me. I told him I was very nervous about the presentation and he replied in a very quiet, whispery manner ‘I do presentations all the time’. I was skeptical and jokingly asked for some tips. He then suddenly puffed up his chest, waved his arms and shouted ‘Ain’t no presentation without caffeination’, lifting up his coffee cup. I learned that it’s not just about alerting your senses with coffee, but being able to come out of your shell and become a bigger, more engaging and confident character when you need to.
