Introverts have a remarkable ability to be independent. We find strength in solitude, and are capable of using our precious alone time to focus and concentrate. A sports commentator once referred to this as “the lonely work” that needs to be completed in order to master a skill. Psychologists call it by another name: “deliberate practice.” In simple terms, it means practicing something over and over again, always focusing on the skill that’s just out of reach, until you get it exactly right.
