Ever thought of bird watching?
Scan an area, ideally a tree where birds congregate or visit; even better if it is around 20m away. Relax, try not to focus too closely on any one point, but be aware of what is going on in the space you are scanning.
When you spot movement, focus in on it. First on the movement, then perhaps on the branch or leaf, then down to the bird (or cat, or squirrel, or plastic bag…). Work towards an ever finer focus.
Now really look. Can you see any more detail? What colour is the bird? It’s wings? Beak? No binoculars.
Watch for a few seconds. Pick out as much detail as you can. Hold that fierce focus, visual and mental.
Then relax, and return to scanning.
