I told my son in law this very thing and I echoed the list of complaints seen here as his future. Being a mechanic myself, some car, some heavy industry. So, I told him to become a boss. Not to loose touch with the wrenches or the technology being introduced. As he should always be ready to take over or show the way to his coworkers, but be a boss and be for the men under him. Joke around and have fun, never belittle!
