The more you travel, the more you can easily assess how much you actually need to pack.

You know what the worst part of vacation is... (besides coming home!) Packing.

I will never forget the first time I packed for a 3 week trip to Europe. I exited the airport with 2 full sized roller bags, a carryon roller bag, and a backpack.  Included in those suitcases were various outfit options for whatever might come up during my time abroad, about 10 pairs of shoes, and at least 6 pairs of jeans. I wanted to be prepared.

I then remember the moment when I needed to take the train from one city to the next.  I looked around anxiously for the elevator or escalator that would take me from street level to where the platforms were and saw nothing. So I made 3 trips up and down the stairs with two 50 pound bags, as frenchmen whisked past me with no offers of help.  

Never again.
