Woods gave up a big piece of that when he left Stanford University after two years, turned pro with a "Hello, World" ad campaign and a $40 million endorsement deal, then quickly became one of the most recognizable athletes on earth.
He will invite some people into that world, but only so far.
Earlier this month in Shanghai, while playing a pro-am round at Sheshan International in a World Golf Championship, Woods allowed that he was staying in a cluster of mansions located on an island in the middle of the golf course. Some of the estates were valued at $14.5 million, and Woods could not believe the extravagance of these homes.
Approaching the island, he was asked which one he was staying in for the week.
"Oh, one of those over there," he said dismissively.
It was a clear example of the world's No. 1 player giving a morsel of insight, but not much more.
Once asked why he enjoyed scuba diving so much, Woods replied: "The fish don't know who I am."
He is friends with many, close to only a few. Among his best friends are Bryon Bell, whom he has known since junior high school, and Jerry Chang, a teammate at Stanford.
When he made history in 2001 as the only golfer to hold all four professional majors at the same time, Golf Digest put him on the magazine cover posing with the four trophies, along with his U.S. Amateur trophy.
Did he keep them on the mantel? A special trophy case? His bedroom?
That remains a mystery.
Even for a magazine with whom he has had a longtime relationship, the trophies were moved out of his house for the photo shoot. That $2.4 million home near the driving range at Isleworth is off limits to anyone not part of his circle.
It's amazing that Woods has managed to keep such a thick wall around his personal life in the 14 years he's commanded the spotlight. The last time his name might have been on any police report was when he was mugged going back to his dorm at Stanford in 1994.
In response to a query on his Facebook account in October, Woods said he and his wife, Elin, had managed to stay out of gossip magazines and tabloids. "I think we've avoided a lot of media attention because we're kind of boring," was the reply.
That changed Friday with a press release from the Florida Highway Patrol that Eldrick Tiger Woods, 33, of Windermere, struck a fire hydrant and a tree shortly after pulling out of his driveway. The patrol described the injuries as "serious," making the news important enough to be the lead item on news channels and for networks to interrupt coverage of college football games.
Then came word of a small photo of Woods on the cover of the National Enquirer, alleging an affair with a New York night club hostess. The woman denied the story and flew to Los Angeles on Sunday to meet with high-profile attorney Gloria Allred.
Woods has had a general distrust of the media since a 1997 interview with GQ magazine in which he was quoted as telling racy jokes in the back seat of a car. He rarely spends much time in an interview, his answers always guarded. If he's not the defending champion, he often will not go to the media center, making reporters come outside to see him.
The only criticism Woods has faced was not taking a stronger stand on social issues, such as the all-male membership at Augusta National, not playing more tournaments, or for cursing and throwing a club during competition.
But in all those cases, it was short-lived.
Questions about his car crash, however, will linger as long as Woods keeps it a mystery. He has dealt with a sporting media most of his life. Now he steps into the realm of celebrity media, which is far more relentless.
Speculation on what really happened that night outside - or inside - his home grows each day. Woods went 13 hours before confirming he was in a "minor accident," then two more days before giving his side of the story Sunday.
He said it was his fault, an embarrassing accident, that he's not perfect, and that any innuendoes were false and malicious. That hardly will be enough to keep the media satisfied.
Woods turned down a request by state troopers to talk three days in a row. Because it is only a traffic accident, he is not required by law to give a statement.
"Although Tiger realises that there is a great deal of public curiosity, it has been conveyed to FHP that he simply has nothing more to add and wishes to protect the privacy of his family," Mark Steinberg, his agent at IMG, said in an e-mail.
But that small camp of TV trucks parked outside the gates at Isleworth might not be leaving any time soon. Woods still is scheduled to compete in his Chevron World Challenge this week in Thousand Oaks, California. As of Sunday night, no one had withdrawn.
Would it not be wise to face the media, no matter how embarrassing, and move on?
That's simply not his style. Woods can be self-deprecating, but only in the best of times. If he chooses not to show this week in California, he could easily go into hiding for the next two months. Hardly anyone saw him in public for four months after his knee surgery last year.
That won't make the story go away. For all the records he is chasing inside the ropes, this might prove to be his greatest challenge.
