I was procrastinating today and decided to compile all the mustard things I could find in my house. I am a bit of an inventory fanatic. On Pinterest I have an entire board dedicated to collections of things including rock crystals, tools, blue things, yellow things, packing lists, you name it. By nature we are hunters and gatherers, we go out into the world to collect things so we can bring them back to our nest. NOTE: this is also how hoarders are born.
Pinterest is an interesting collection database in this way. No need for mountains of magazines or collage books of torn pages. Every image ever taken is probably on-line and now YOU can categorize and save right where you want it. I wonder, does it keep us from bringing actual things home? Or does it facilitate easier hunting? I find the action of "pinning" gives me a sense of ownership, as though having this photographic image on my board is equal to experiencing what it represents. In a small way it can satisfy those little nagging urges to go shopping or take a trip.
There is certainly a therapy found in sorting and placing. Why do people clean or re-organize their tool shed when they are aggravated or want to be alone?
