“Great leadership has many different attributes, but it starts with knowledge of a particular pursuit, because without the knowledge and mastery of that particular pursuit, I don’t think you have the authority to convey it with conviction to others. It usually is associated with an obsession, because to be a great leader, you have to be obsessed by something, otherwise everything seems false and hollow. You have to then be able to convey your obsession to people in a manner that inspires and encourages and motivates them to perform at a level they didn’t think they were ever capable of performing at. All of those, when knitted together, help to define what separates a great leader from a very capable manager.” ([View Highlight](https://read.readwise.io/read/01h9fgfs3rmd4e2ay8w7xf6f62)) Obsession causes depth and passion, which is required for innovation and motivation for employees.
