If you ask me before I take the two months off, I would plan to write a novel, write, shoot and direct a movie, take the CFA, back test some trading algorithms, and write three apps (one game, one very useful app in a new industry I know nothing about, and some social app) while learning new languages (mandarin and some variant of lisp). If you ask me after the two months, I most likely caught up on Westworld.
