I’ve had a shopping list for the last 8 or so years. It’s written in Notes and accessible to me on my phone or iPad. I add items though a year and sometimes delete if I change my mind. Generally, it is a list of reminders, kind of “needs and wants”. I feel certain satisfaction when I cross an item from the list. But analyzing last year purchases and had to stop and think. How I bought more than I planned and only a few pieces from the list? So, I looked closer at my shopping list. I can have two distinctive types: one is wants like “solid color summer pants” and other is more precise needs “white wide leg linen pants”.
I edit the first type all the time, I sometimes add too much or decide that it is not needed. These are more like ideas and I’m not surprised that I might not buy a lot from this category.
