I’d love to hear about your quirky habits.
One of mine is that when I’m out in nature I tend to collect cool looking rocks, sticks, cones etc. My window sills have become a geology exhibit (and I have zero clue about what I’m collecting, I just go by “ooh shiny”) and more often than not I’ll have small rocks in my pockets, bags, backpacks etc etc
I usually only carried my water bottle. I’d plan most medication to be taken at the end or beginning of the day. My wife recently converted to a Michael Kors backpack purse after years of having an over the shoulder bag and loves it. She says her back is much better with a balanced load instead of just one side.
