A framework by David Perell
David Perell's Personal Monopoly
A personal monopoly is the position of being the only person who does what you do. David Perell, who founded the Write of Passage writing course, took the phrase from Jerry Garcia and built a career on it after being fired from an advertising agency at 22. The underlying claim is a career risk assessment: any skill legible enough for someone else to copy is a skill that will not hold its price.
