If I could work 55 hours without having a nervous breakdown I would definitely go with the job I loved. 40-hour jobs that mean nothing just wear one down. The weekends aren't useful because Saturday is recovery and Sunday is dread. I'd much rather be excited but a bit tireder most days than stuck in a grind day in and day out.

Might be worthwhile to look up a tenant union in response to the landlord screwing you over. There may be ways to make him uncomfortable even if you don't take him all the way to court.
