Your "get over yourself" and "mature person" bits fill me with frustration and anger. I'm sorry for that, but it's there.

Being selfless is great. Hating the grind of a 40 hour / week job, versus "accepting" it has nothing to do with selflessness.

I didn't say being more selfless meant becoming a slave to your employer. I clarified in another post that becoming more selfless can actually help you to leave a toxic environment too. Or maybe you might realize that you were part of the reason it was so toxic, and you take that with you wherever you go. In that case running doesn't help. I don't know what OPs situation is or what yours is. Once you let go of yourself a bit, and readjust your mindset and priorities accordingly, based on whoever you are and whatever situation you are in, then it will likely become more clear what you should do. And it will be easier, and even enjoyable, to do what you should do.

I don't think we were designed to be miserable, so if we are stuck in misery isn't it logical to think we might be pursuing joy in the wrong things?
