My old job had me working 13 hour days. It was only supposed to be 6 days a week, but it turned into 7 more often than not. I was a horse trainer/professional rider. And on competition weeks, forget it. I would be up at 3 in the morning to get out the show grounds by 4 so I could have everything done when it needed to be. Eventually I was able to hire a groom to help out, but I still ended up doing a lot of that work on my own (if you want something done right, you do it yourself). So on show days I was up at 3 and stayed at the competition until whenever my last class ended, usually sometime in late afternoon. Then I still had to make sure the horses were fed, stalls were cleaned, and everything was set for the following day, so I wouldn't get home until 8 or 9. Try doing that Wednesday through Sunday.
