So 4.5h for commuting, 9h of work, 8h of sleep, that leaves just 2.5h for everything else in your day, including enjoying your rural lifestyle. That would drive me absolutely crazy.
Remember, 4 of those hours of commuting are sitting on a train. You can watch movies, read books, take a nap, play games, get work done, etc.
I usually was at work from 10-5 and usually sleep closer to 6 hours a night. That gave me about 6.5 hours of free time. I also worked from home twice a week.
I personally hated it and only lasted at the job for a little over a year, but I could understand how some people could make it work.
