I was thinking of expanding my vocabulary, how about that?
Read philosophy. Knowledge for its own sake is useless. Draw your own conclusions from the ideas you read. Someone else's context won't be yours.
fwiw, I never took a formal philosophy course (or any arts except music) in my life. But I read widely. That is key.
Second thoughts can generally be amended with judicious action; injudicious actions can seldom be recovered with second thoughts.
