I'll be completely honest here...I believe that years 6-10 are the most difficult in our field. During that time, I had become a head director for the first time and felt like I was nowhere near prepared for the job. Because of that, I overworked myself instead of working smarter. If you find that you are at work more than you are at home, you definitely need a change. Whether that is a change of workplace or a change of hours and obligations is up to you. I wish you the best. If you hang in there, it will get better. Please prioritize your health over your job!
