I am obsessively thinking about what life would be like if I got the market manager position

I hope you get it if it's right for you.
Twice I went for promotion. 1st time I got laryngitis the day of the interview. The 2nd I didnt get the job. But, I was so glad I didn't but got the experience for it. I wish you all the best, either way.

You're taking a balanced approach. That's good. I'm thinking you'll be offered the position.

Great way to think about it
