Something I realized is that with a lot jobs I interviewed for in the past, I never really wanted the job.
At the time of the interview and shortly after, I really hoped to get the job, and may have had my heart set on it, but in hindsight I never really wanted it.
It was more of an acceptance/rejection thing. Also, I was caught up in the game. Like that Bachelor show, where the contestants may just want to win the game, and they're not necessarily in it for love.
