I need a crafty idea

Hmmm....if I were going to add something I would want it to be something that would not be considered junk to throw away once I got home. While story stones would not be junk in my mind, I just don't see me using them at home. I saw the phrase, "Heal yourself, heal the world." That gave me the idea of making a mini first aid kit. kind of a little tiny coin purse with small first aid items in it, like a band aid or two, a couple of aspirin and a rolaids. That would be something I would keep in my purse for a long time and I would replenish the items in it. I would not have to be expensive. You could do the straw trick for first aid ointment, roll aspirn in tin foil etc. The containers could be pill bottles, altoid tins, little zipper bags, or small boxes.

While I love this idea, I personally wouldn't use aspirin or ointment outside it's original container so I'd see about getting those little mini packs of neosporin/aspirin/alcohol wipes/etc.  I'm sure you could probably find them on Amazon or maybe a medical supply store.  Kinda depends on how many you need to make and what your budget it.

How about the painted rocks that people leave for people to find?

I like to use the computer when making mass trinkets for strangers. It's easy to make it seasonal and specific to the event.

What about combining ScrapbookMyLife 's ideas? Make a postcard with cut slots for holding a tin of mints, or something else useful like a small roll of Advil or toothpaste.

Maybe it's my stage of life, I don't like to spend a lot of time on handmade items if I don't know the recipient appreciates it, and I'd rather receive a consumable than a trinket. I also feel guilty when I know someone spent time on a handmade gift, but it's not my style.
