PACKING VS PANICKING
It helps, when leaving the country, to take off the day before departure as well as the day-of.
That way, you can finish the last-minute shopping.
You can carefully sort and stage the goods to be packed near the appropriate suitcase while watching TCM, which is screening films such as "The Spirit of St. Louis" (good), "Yankee Doodle Dandy" (also good) and "1776," a 1972 musical about the writing of the Constitution, which features a sweaty Benjamin Franklin with a low, low voice perfect for voiceover work and an entire song about who's going to have to write the darn thing (ouch!).
Also, you have plenty of time to worry about the single carry-on bag you're allowed to bring, and whether or not it meets the weight requirement.
