John Lee Dumas (JLD), founder and host of the Entrepreneur on Fire podcast and author of Common Path to Uncommon Success, has some great entrepreneurial lessons in his book that we can apply to cold calling.
When John Lee Dumans first thought of starting a podcast, he had the idea of producing one episode per day. His friends thought that it would be impossible to produce so many episodes in such a little amount of time. There weren’t examples of others attempting this because most people weren't sure how an audience would respond to so much content every day.
