I can't say I hate my job but I have zero interest in it. Where as I had lots of <$100k jobs I loved. My life was better. I only get one life. I'd prefer to live a happy life than a well paid life. Right now I get paid well but my life feels like it's just bleeding away as a drone.
The biggest reason I haven't pulled the trigger is there's no guarntee that taking the $70k will actually be fun this time. I have my criteria for taking the jump though and if they're met I'd do it in a heartbeat.
