Olympic figure skating champion Kim Yu-na may skip the upcoming World Championships in March in Nice, France, she said on Thursday.
"In order to compete, you have to have a clear goal and be mentally prepared for it," said the 21-year-old. "But I don't know exactly what I want to do at this point."
Kim was speaking at an event in Los Angeles to announce the city's successful bid to host the 2015 Special Olympics. She is a global promotional ambassador for the Games, the largest athletics competition for the mentally challenged.
She also hinted that she is still agonizing over whether to retire from the sport or remain competitive.
Unsure about her future, Kim skipped the ISU Grand Prix Series -- which runs from October to December -- last year and started preparing for the World Championships from October, three to four months later than other skaters.
She collected a silver medal at the Worlds in Moscow in May.
But Kim has fallen even further behind schedule this year. Not only is she skipping the GP Series, but it is uncertain whether she will compete at next year's Worlds.
She left Korea for LA at the end of last month and is currently training at the East West Ice Palace without a coach as her contract with Peter Oppegard has already expired.
"I am in good form, practicing two to three hours a day," she said. "I will decide whether to join any competitions when I'm mentally and physically ready."
