proluctance

n. the paradoxical urge to avoid doing something you've been looking forward to—opening a decisive letter, meeting up with a friend who's finally back in town, reading a new book from your favorite author—perpetually waiting around for the right state of mind, stretching out the bliss of anticipation as long as you can.

Latin pro-, forward + reluctans, resisting. Pronounced "proh-luhk-tuhns."
