When I had this type of job/life, I didn't hate the work, I didn't hate the people, sometimes I loved it, being on the water, early in the morning in the summer, working on a mega yacht.
But, the time, was what got to me. I spent all my time at work, preparing for work, or the fall out from work, doing laundry, cleaning, grocery shopping, there wasn't a lot left. I would lay awake at night and think this my time for myself, I can lay here and no one can tell me what to do or where to go, for these 30 minutes.
