One interview can test one story
A focused session can become a sample chapter. It is not enough to cover an entire life.
Split a full book into themes
Childhood, school, work, family and turning points usually need separate conversations. Our full family biography starts with roughly six to eight themed interviews; actual scope varies.
Plan additional voices
Each relative adds evidence and perspective, but also names and facts to check.
Leave room for a second pass
After a first draft, identify missing scenes and people. A targeted follow-up often helps more than a single marathon recording.
