A job is just a way to pay the bills. If it's low stress and pays well then keep it, BUT you need some hobbies to keep yourself mentally and physically active on your own time. The danger is when you spend work doing nothing then get home and do the same nothingness. I fell in that trap myself. You get complacent with just relaxing all the time then it turns into depression. In my case it was a combination of things. Lack of daylight was probably a big factor. I'm not a morning person and sleep in on my days off. If I sleep in too much then I wake up in the dark. Our days are very short most of the year so you need to get up early enough to see it.
I recently finished building a shed, still have finishing touches to do, but projects like that keep me going. I spend dead time at work researching stuff that's hobby/home project related to keep inspiration going. Funny thing is though I tend to be more motivated to do those things while I'm at work, when I'm home I just want to relax, but have to force myself off my butt and once something is done there is a sense of satisfaction.
