What I should have said, to avoid coming across harsh is: "try googling the app because part of the secret to reducing pack weight is actually going through the process of thinking about each item and actually weighing it, then use it in the field and adjust". And by that I mean in part, start from a blank slate but use the super cool slick visually friendly lightpack app.
I have a half dozen excel spreadsheets going back a few decades covering almost every item I would or have taken in the field, coded for season, coded for primary or secondary, coded for type of hunt etc. Also broken out for my hunting buddies to make sure they know what I'm bringing and what they are expected to bring. And despite all my Excel lists, I like the lightpack app so much I'm going to try loading my gear for this year's scouting trips into it and see how I like it. It is just so "clean". Also because my "virtual garage of lists" (and real garage) is overflowing and cluttered (meaning, I have so many lists I need lists of my lists...so this would be a good chance for ME to start fresh).
Seriously, the process is part of the cure, that's why I said go to the app and start with a fresh naked sheet. Weigh each item. P.S. , then use a permanent marker to write the weight on each item. I often put it on the labels of clothing. I weigh every isobutane cartridge with a starting weight so I know how much fuel is left after a trip and can decide if I want to relegate that can to future car camping or bring it on another backpacking trip.
