As a Non-Commissioned Officer, I was in charge of two Marines. Balance of Life vs Work was adequate for personal time, however it is difficult to attend college. My co-workers made the job fun and worthwhile.
The hardest part of the job is teaching a class where the students are unwilling to learn. To overcome this challenge, I would make the information relevant to the students and show enthusiasm for the class.
The most enjoyable part of the job is the final exercise to evaluate knowledge learned. The final exercise consists of a mock CBRN incident. Seeing the students react successfully to the incident is rewarding.
