I want to thank everyone for their comments, their support and their understanding. I've decided not to tell my boss. If he finds out, he finds out. He may think less of me for not telling him but who knows? At this point, he should know what kind of person I am (I've worked for him long enough) and he should know my second "career" hasn't affected my job yet, so why should I have to worry about the risk of telling him?
With that in mind, I'm going to keep doing what I'm doing...my love of writing. It may mean I can't promote to my local library, but there are plenty of other places to go that I haven't ventured to yet. Many of the people I work with are pursuing their dreams, they are doing exactly what they want to be doing in life, or at least somewhat, so they should understand.
With that, I leave you with two Eleanor Roosevelt quotes. She said some pretty awesome things in her lifetime:
No one can make you feel inferior without your consent.
The future belongs to those who believe in the beauty of their dreams.
