It's awful waking up and dreading going to work, no matter what sort of money you are on. I've been in sh!tty jobs paying good money and moved for less pay to be happier, thankfully I have the best of both worlds where I am now, the money isn't the very best out there but it's not far off, and I can honestly say I have never woke up and thought 'I really don't want to go in today' (hangovers aside of course)
Happiness is a must for me and the wife, she was doing architecture for a building company, she had 2 years left to do to become fully qualified and a starting salary of around 40k, not too shabby!!
However, her 2 bosses were..... How can I put this nicely?? CIINTS!!!
They made her life hell, to the point she was coming home crying, couldn't sleep and hated the thought of going into work, she had to physically stop me from going to her work and knacking the 2 pricks on more than one occasion!!!
It got to the point she couldn't do it anymore, left and became a childminder, he'll of a career change lol
The money is nothing like what she could have been earning now and our house has a load of kids running around it all the time but it pays the bills, she is her own boss and she's never been happier.
Happiness all the way I'd say but decent money for a job you don't mind is probably the way to do it.
