I've found a good way to help remember if I've taken my vitamin for the day. (I have to take the vitamin with food, and I don't eat regularly enough to simply take one with a particular meal.) I keep the bottle in a cabinet and, on even-numbered days, after a take the vitamin, I turn the label facing out. On odd-numbered days, after I take one, I turn the label facing back. This requires an adjustment on months with 31 days (or a February in a leap year), but that doesn't seem to be a problem. Actually, the biggest problem is remembering what the heck the date is. But I like my system.
Not all of my Little Things are about Sammy, you know. Little Things are minor, everyday actions, objects, and experiences that add up to a life full of deliberately chosen values. I used to think that if you spent your time applying your mind to the acquisition of these Little Things, that you'd necessarily be sacrificing your higher values, but this is wrong. It's true that we all have a limited amount of time, and even a limited amount of room in our conscious minds, so we have to have a hierarchy of values. But the sum of all the Little Things in one's life does add up to a great whole, and our pursuit of these things can bring great meaning and fulfillment to our lives.
