More generally, this case raises questions about great jobs and meaningful jobs. From all appearances, Tillman had a great job that he left for one he found more meaningful. These concepts are worth pursuing. What are some "great" jobs? Would being a star in the NFL be a great job? Can you list some other jobs you would consider great? Are there any similarities? What makes a job "great"? What are some jobs that you would describe as "meaningful"? Why might serving in the military be meaningful? What makes a job "meaningful"?
This is also a good opportunity to reflect on your own career choices. What job do you see yourself working in five years? In ten years? In forty years? Were there any overlaps between your list of great jobs, meaningful jobs, and jobs that you are likely to hold? If not, why not?
