Independent workers have many freedoms, but this reduced oversight from others comes with its own challenges. As explained by Grant (2018) in his podcast, independent workers can build structures to help them stay on task and be successful. Which of the following is not one of these four structures? a. Structure, or routines that form something of a regular schedule. b. Purpose, or reminders of why one is doing what they are doing. c. Place, or a specific space where productive work can occur. d. Control, or a monitoring system that assists with holding one accountable to meet self-set deadlines. e. Interaction, or conversations with relevant others who can offer encouragement and mentorship
