Imagine opening a new tab before remembering why you opened it. A moment ago, you were doing something else. Something drew your attention across.
An average from a study is not a personal attention limit. It cannot tell you how long you can concentrate, or explain every time you switch tasks.
The immediate event can be more informative. Was there a message? A difficult sentence? A question you needed to answer? A familiar opportunity for something easier or more interesting?
You do not have to score the answer. You could simply return to what you had chosen, or decide that the new task genuinely matters more. The point is to make the choice visible to yourself.
AATAM’s mission gives inward attention an enjoyable place in the day. Morning, afternoon or evening are ways to find room for it, rather than a prescribed routine or a promise to repair your attention.
