Yep, that's macro as I remember it

After finishing a month-long series in "old-school" macroeconomics <insert IS-LM memories here>, a professor in grad school pulled together all of the differential equations and their neat, closed-form solutions on the board and said, "well, that is all good and well, except in real-life you don't know where you started, you don't know where you are, you don't know what previous shocks are still working their way through, and you don't know where you are going."

Macro doesn't seem to have changed much since I took it over 25 years ago.
