Once you start feeling you would rather be doing something other than what you ARE doing, it is time for a change ...
I worked for the same company for 40 years ... had a good job, a great staff, and a good boss who left me alone most of the time, but was there when I needed him ... when I started feeling bored with the job, I knew it was time to retire ... don't know when (if?) I'll ever retire from gigging, but no doubt that will happen at some time ...
Best of luck in your decisions, Gary ...
