Yeah, you should. You will always feel worse with yourself for not having the balls to quit and try just because of the easy money you have now, unless you are an empty shell of a human being which you don't seem to be. We need other things to actually feel like we have lived and seized the day and all that, which is something we tend to care about a lot as we get older. Speaking from experience (I started a new career at 35, and don't regret it in the slightest).

I feel this post OP. Same boat. Way back when I was a teacher I had no money but life was so fulfilling and I was always happy to go to work. Now it's the opposite... Buddah said something about 'right livelihood '

Death to America

If you can afford to pay your bills with that salary and you think that you would be happier fucking do it. We don't live very long and we work most of it. with drive time I am gone from my house 11 hours a day, after putting my kids to sleep I only have 2 hours a day to myself. Only 2 hours of my day where I can sit down and just relax. If you can at least be happy and that other 11 hours good on you do it. Only person's opinion that matters is yours and what makes you happy

testing and stuff (half of teaching I think due to hell society thinking that's what teaching is when it isn't) is also bullshit so i suggest using the money to support people who struggle under our current education system (neurodivergent people and such) and pick up a personally meaningful or even community based hobby like baking or idk like organizing events
