I like to have my own little way of conceptualising the spoon theory, because some tasks take much more out of me than others, but I am usually able to complete roughly the same number of little tasks per day. For me, I visualise this in the form of teaspoons and tablespoons. On a normal day, I probably have about 4 tablespoons, and about 6 teaspoons.
