Here's one: going to the grocery store (or farmers' market) every day, to buy a little of this or that to make dinner.
Years ago when I lived in San Diego, I blushed when a cashier bid me farewell with "see you tomorrow!"
Now I'm at peace with my grocery habit. I don't buy shoes, or expensive jeans, or computer gadgets...
Polishing off the last head of broccoli is usually what compels me back to the store.
What last bite compels you?
