I am focusing on gratitude.

Focus implies effort and it implies exclusion. To bring one thing into view, everything else has to go soft.

That is the actual work here. Not pretending the unpaid bill does not exist, but choosing, for a minute, to look at something else instead. The fact that you have a place to keep the bill. That the lights are on to read it by.

Attention is a small budget spent all day, mostly by default. Directing even a fraction of it on purpose is a decision, and one of the very few in a day that nobody else can make for you.
