I've long wanted to study logic in a formal setting.
[Cue readers to say: "We've also long wanted this for you, John."]
Alas, I cannot take a class for the foreseeable future, so I shall read a book on the subject by a professor of logic. I picked up this introductory text, which has not been revolutionary to me, but has given formal names and processes to things I've already thought about.
Have you ever formally studied logic (as in a classroom setting)? What was it like for you?
