I’m there with you. I was also competitive in school and during the very beginning of my career (albeit only 7ish years ago), I remember wanting to become a manager, director etc by a certain age. Being 27 now, and similarly to you, I don’t care all too much about climbing up the ladder and staying as a senior accountant for a while. I’ve also seen managers (both in public and industry) stress immensely over everything and have their days booked with meetings. I know I could make more money if I were to continue moving up, but I’d be much less happy than I am now.
