What does a sporting legend do when they walk away from the cut and thrust, the adrenaline fueled buzz of top flight competition?
In many cases they make a comeback in an attempt to rediscover former glories and some like tennis player Kim Clijsters, who won three more grand slams, make a success of it.
But more often than not in ends in failure, with seven-time Formula One champion Michael Schumacher, who quit for the second time at the end of this season, and multiple world boxing champion Ricky Hatton, knocked out in his comeback fight, recent notable examples.
In golfer Annika Sorenstam's case, you get "busier than I've ever been" and pursue a business career while running a foundation and looking after a young family -- all with the inner drive and determination that took her to the top in her chosen sport.
Her decision to quit back in 2008 came as a shock. She was only 38 and still a contender at the highest levels, but once she made the break it was total and final.
Her last competitive event was in Dubai in December of that year and she has not trod the professional fairway since, marrying her second husband, Mike McGee, in 2009.
They have two young children, Ava born that year and William in 2011, who arrived 13 weeks premature, but thankfully with no ill effects.
But through her commercial and golf design interests, promoting the ANNIKA brand of clothing, Sorenstam is still heavily involved in the game she loves.
Timing in business just like golf is everything and the Swede told CNN that launching new ventures in a global recession was "tough."
But she was not going to allow something as trivial as economic turmoil to divert her from her goals and Sorenstam has put her name to a growing portfolio of signature golf courses, mostly in Asia.
Back at home in Orlando, Florida is the base for her academy, where players of all standards can sign up for tuition, and her non-profit making foundation, which offers young golfers opportunities to fulfill their potential.
She also has an interest in a winery and financial group, as well as making occasional appearances on the Golf Channel.
Like her male counterparts such as Arnold Palmer and Greg Norman, who have built up business empires off the course, Sorenstam believes the work ethic is the key.
"There are a lot of similarities with the things I learned on the golf course, such as focus and determination," she told CNN. "Without drive and vision you can't start anything, it's a little bit in you."
Sorenstam retired just at the time when Asian players were beginning to dominate the LPGA Tour, including World No.1 Yani Tseng, who the Swede has mentored. It helps they are near neighbors in Lake Nona.
"I share my experience of what it's like to be at the top, to always look at the big picture," said Sorenstam.
She believes that the wave of success that Tseng and others from the region are riding, will continue after Asian players won all four of the women's majors in 2012.
"They have tremendous support from their families, are prepared to start practicing at seven o'clock in the morning and stay there all day," said Sorenstam.
