Sitting in meetings might seem like an implementation detail to you, but it's dreadful for a lot of others. I don't think it's sad when someone decides they would rather not be a manager, I think it's normal. I also think it's not sad to decide leadership is an uninteresting prospect. People need to be led but you have needs yourself, and it's alright if those needs don't line up with leadership. It's okay to just be a person with a job.
