Move from broad context toward a small set of high-value questions. Tim typically budgets two to four hours, asks guests for favorite long-form interviews and exploratory topics, follows unusual details and citations from Wikipedia, checks recent social posts for sensitive life changes, and studies previous long-form interviews. Past appearances show where a guest excels, stalls, or repeats polished greatest-hit stories. Mutual contacts can suggest roads less traveled. The host may deliberately cue one proven story early to earn attention, but should preserve substantial virgin territory. For a 90-minute interview, Tim selects only five to seven priority questions and leaves room for side doors. Unused research is marked for a later round rather than forced into the current conversation.

How to run it
- 1
Set the preparation budget
Allocate roughly two to four hours for a normal interview and expand only for unusually important opportunities.
Watch out Do not treat an exceptional multi-day research effort as the default.
- 2
Solicit guest inputs
Ask for two or three favorite long-form interviews, possible exploratory topics, and any useful preparation material.
Pro tip Collect these weeks or months before recording when possible.
- 3
Search the unusual edges
Find an esoteric detail in the guest's public biography and follow its citations.
Pro tip Tiny details can open questions that previous interviewers missed.
- 4
Check current context
Review recent social activity for major personal events or public controversies that affect the conversation.
Pro tip A month or two is often enough for a basic check.
Watch out Do not walk into a sensitive event unknowingly.
- 5
Map prior performances
Study long-form interviews to identify strong stories, unanswered areas, and topics where the guest stalls.
Pro tip Ask directly for a story that reliably gets a response, without hearing it before recording.
Watch out Do not fill the whole interview with material you already know.
- 6
Find less-traveled roads
Ask mutual contacts for questions and topics likely to produce a different conversation.
- 7
Select the vital questions
Choose five to seven questions for a 90-minute interview and allow room to follow promising side doors.
Pro tip Mark unused material for a second appearance.
Watch out Attachment to every research note produces a rigid, rushed interview.
In the wild
Tim spent four or five days on a potential breakthrough interview, consuming interviews, films, books, and other material because he wanted to be the best-prepared interviewer Schwarzenegger had met. He still preserved unexplored territory rather than merely replaying known answers.
→ Deep preparation supported original questions without eliminating genuine curiosity.
When a guest identifies a story that always gets a strong audience response, Tim places one such story within the first ten minutes to pull listeners in and pursue the driveway test.
→ A proven story creates early engagement while the rest of the interview remains exploratory.
Common mistakes
Trying to finish every question
Ninety minutes passes quickly, and forcing every note removes the freedom to explore better side doors.
Knowing the entire conversation
Preparation that leaves no virgin territory makes the host less genuinely engaged.
Is it for you?
Best for
Long-form interviewers preparing for guests with substantial public material.
Not ideal for
Short news interviews where exhaustive preparation would become obsolete immediately.
