Focusing on the positive is easy for me.

A camera in a dim room hunts. It racks back and forth looking for an edge sharp enough to lock onto, and against a plain grey wall it never settles.

Attention behaves the same way. Positive is hard to focus on because it is usually vague — a general sense that things are basically fine, which is nothing to grip. Give it an edge and it gets much easier: the specific colleague who covered for you, the ten minutes on the step before the house woke up. Ease comes from having something particular to point at, not from trying harder to feel good.
