And after you enjoy that sweet mobility and freedom, you'll never go any other way. Spread out everything you think you might need on the living room floor. Pick up each item one at a time and scrutinize it. When in doubt, leave it out.

Packing list applies equally to rucksack or suitcase travelers.
Bobbling down the cobblestones of Rothenburg, you'll know what I mean. I live out of one of these for three months at a time. Entire books are written on how to pack. The bulk of your luggage is clothing. Minimize by bringing less and washing more often.
