It's an interesting thing.
A person, say you, can be quite addicted to sugar, or mindless tv. But, if you can manage to wean yourself off long enough, you'll come to find that it's hard to go back without a strong reaction.
You become sensitized again.
And you may also come to find that those cravings become replaced by (or re-emerge for) a desire for sights and sounds and tastes and smells and input that nourish your body/mind/spirit, rather than just temporarily pacify.
Just a few days before drummer and teacher, Jim Donovan, emailed his annual question, "What is your word for the coming year?" I had decided on mine.
Or, it decided on me.
Because I wasn't thinking about it. It just felt delivered, like a whispered message, while I was totally just doing whatever I was doing.
