New Job

Well, I sent out two resumes and got one reply resulting in a job offer.  It is a promotion, more money and half the commute.  Tomorrow I must resign from my current job and I'm freaking out.  I adore my boss but the work has become unsatisfying.  I'm ready for change but I am panicking to have that conversation.   There's no room for emotion in business, right?   I love change but I'm out of practice.
