sorry i don't believe in luck, however i believe luck=when preparedness meets opportunity.
you have the opportunity..are you prepared?
do you know everything about this library, it's mission, it's vision statement, the communtiy it serves, is your resume impeccable?
have you been on its website? what is its history?
do you know the names and positions of your superiors?
what can you bring to the job as attributes?
that's what gets you hired.
