If one is unhappy and always complaining about their job they should do something about it. BUT I know a number of people who hate their jobs but do nothing about changing it. A lot of people are just lazy and/or not willing to change; I saw this where I worked.

I worked in R&D for 39 years and loved it most all of my time there; the last couple of years the bean counters took over R&D and ruined it. I also loved being a weekend musician warrior. However if I didn't like what I was doing I took steps to improve my situation. I went from a machine operator to a lead technician with patents by accepting change.

Happiness is up to you, i.e do what you love or change.

I think my wife has started to show the first signs of dementia.
She said she can't remember what she ever saw in me!

64 bit Win 10 Pro, the latest BiaB/RB, Roland Octa-Capture audio interface, a ton of software/hardware
