"Professional success?" Not sure I qualify for that lofty title. I do have s ready job and health insurance. Duke English help me to learn how language shapes ideas and vice versa. So I'd say I'm better than average at being precise about my own ideas and deciphering other peoples'. That includes figuring out: (1) how not to get in trouble with the boss, (2) what my spouse actually wants, and (3) how to get the audience to laugh at Shakespeare's 400-year-old jokes.
