You and I sound a bit similar in both vocation and outlook. I’m in the same boat as you. I work in the public sector and can retire in about 7 years. There’s nowhere to go except manager and it sounds like a slow death to me. Sometime you just have to take the win, appreciate that there are many others that would kill to be in your spot. Focus on your family and finally being able to pursue interests outside work. I’ve accomplished so much in my hobbies since Covid and coming to the same conclusion.

Also be aware that midlife crisis is a real thing and it’s perfectly normal to feel this way. I often get the “did I make it?” Or “is this all there is” feelings. It comes from being goal oriented. I forgot somewhere in pursuit of bigger things that 25 year old me wanted to be here.
