My considerable efforts to the contrary notwithstanding, it is clear to me that some people take the wrong message from my OneBag.com site. Usually they do so as a consequence of a superficial reading of the information to be found there. Arguably the most important advice there is to be found on the "Using a Packing List" page, which attempts to make the case that if you have nothing to measure, you have nothing to control. The section people tend to focus on is the "A Packing List" one, which lists examples of the items that are on MY packing list (note the title's use of the indefinite article); there is no stricture, however, that they should be on YOUR list, only that you should HAVE a list (see first point).
