No news is good news...?? Who believes that?

So, i haven't heard back from the hiring manager yet.... I'm trying my hardest to not worry about it, not obsess about it... But that is very hard for me to do!! I have been spending a lot of time thinking about this choice,,, hoping that the path will be clear, and I'll know the right thing to do... I'm also afraid he's going to call back and rescind the offer...
