There will be a lot of nights you'll be working. As a boss, you're going to have to get over that. Everybody in this place gets criticism. Show a lack of confidence. I doubt you're really the right person, but we haven't got anybody else.
Somebody has to fill the job.
Since every person beginning a job has never done it before, it's easy to tell somebody he or she is not qualified. Expect results too soon. In a couple of weeks, you ought to be on top of this job. I'm not going to be able to give you much help. You're going to be out there by yourself.
