Dream Job Rejection (Part 2)

I noticed something strange in the process of interviewing and getting all excited about this job (6-12 months ago I wouldn’t even have allowed myself to dream of this high level job). In my vision of getting the offer, I kept picturing all these different people I would tell about my new job (including giving notice at my totally fine current job). Friends, family, colleagues. I don’t know why this was my picture of success, like finally I would be seriously proud of what I was doing? Am I just trying to prove something to other people? I believe people mostly think I am at least moderately successful now but I guess this would be a new level of success. Did I really want this? Yes, I think so. But apparently I also really wanted to impress others. Is that something to accept or something to work on moving away from?
