Yeah, try having a job that does both, and has incredible time pressure. 18 hour days are the regular, my main metro area of work has regular 2 hour commutes, outside in heat, cold, different locations, physical danger, intensely mentally and physically challenging. Longest day I had was 26hrs with a 500 mile drive mixed into it. I also have to do my own bookkeeping, insurance, gear maintenance. I live off of ibuprofen and caffeine. Cry me a river about your desk job.

I work in TV and film.

It's more challenging than most my OIF OEF tours of duty which in themselves were doggedly brutal (18 hour work days in a 120 degree 100% humidity engine room, 7 days a week, 6 months at a time). So 136 hrs a week, and that's not including being woke up to lead a fire party, or tomahawks flying overhead, or gas gas gas, etc etc...

About 90% of the people that start doing my job on set are out of the industry or my job in a few years, if not months, sometimes a day or two is all it takes to break a FNG's will. The ones who stick with it, myself included have some weird mix of awareness, heart, endurance, and acumen to make it work.

Yeah I'm bragging a bit, but it's fucking true, if I had a way out of this industry I'd jump at it, but hard to walk away from 60-300 dollars an hour!
