"I hated having 85 employees. It had become a little hell. I needed to get away and clear my mind."
How sad to hear from their leader that he hated having to deal with them. Being in management and leadership positions means having a degree of power over the employees, but it also comes with a responsibility for those employees. Employees are people and not just pawns to fulfill the manager's whims.
Before accepting the job of a manager, think about what that position means because it can be very different from what your existing role is.
