You cannot stare at what is missing and expect gratitude to grow beside it.

Gratitude and inventory of the missing cannot occupy the same attention, and one of them tends to be the default. Staring at the gap keeps it in the foreground, and no amount of being told to feel grateful will work while the gap has the focus.

Rather than trying to feel differently, change what you are looking at. Name three specific things present in your life today. Feeling follows attention rather than instruction.
