Moving to Chicago

So, if anyone has moved recently, what were the aha moments you had as you unpacked. Essentially I'm looking for the key things you said "I should have made this easier to find, tagged or were key important things you wished you had done.
  1. Looking for learning points here.
  2. Mistakes you wished you hadn't made.
  3. Things that made your moving easier.
  4. We are moving in a SHORT time period
  5. Thanks in advance...
