I'd think an actual biography made in universe would focus a lot more on those areas.
Yet actual biographies,
especially autobiographies, tend to concentrate on the
lesser-known aspects of the subject's life. Think about Alex Trebek's
The Answer Is . . . : it dwells a great deal on his years growing up, his years in radio broadcasting, and his years hosting mostly-forgotten game shows, before it gets to
High Rollers and the 1984 revival of
Jeopardy!, and even then, it goes into some detail on what he was doing when he wasn't hosting game shows.
Speaking of Trebek, and
Jeopardy!, every time I find myself expecting Johnny Gilbert to announce Trebek, a split second before he announces Jennings, I reflect back on how, for the first few years of the revival, I was expecting Don Pardo to announce Art Fleming!
Likewise, the few ST actors who've written memoirs or autobiographies tend to dwell an awful lot on the stuff most people don't know about them. Ditto for astronaut biographies and autobiographies.
Meanwhile, I'm about halfway through reviewing my own opus, taking the time to not only timeline every significant event (in the process, finding a few conflicts, and a few important events that had never made it onto the page!), but to create a reference spreadsheet listing every character, every important definition, and my protagonist's University coursework. And of course, to enter the revisions and corrections into the actual files (usually in Ventura Publisher, so I can see right away if something's going to screw up the pagination).
And I'm also about a third of the way through re-reading CLB's
The Face of the Unknown. It seems like every time I re-read it, I've forgotten enough of it to where I re-experience the wonders of CLB's world-building. But I still have this picture in the back of my mind of a young princess with a distinctive hairstyle walking into Mudds (from LD: "The Inner Fight"), asking to see the Information Broker, and on meeting him asking, "Aren't you a little short for a Dassik?"
