Celebrities fed off of the love and support that their fans send them, and athletes could also benefit from a big cheer from the crowd.
But just because these two professions have something in common, it doesn't mean that making a transition from one job to another would be an easy task.
However, these seven celebrities were brave enough to take the leap and eventually made a huge success in other fields.
Let's meet these brave stars who turn a crisis into an opportunity of a lifetime.
1. KEY of SHINee
K-pop boy group SHINee's member KEY was a promising water-skier back in middle school.
Even though he is not a big fans of sports, he managed to win a medal at one water-ski contest when he was on his city's water-ski team.
In 2015, KEY mentioned during an interview with the press that he recently started water-skiing again and it was just like riding a bike.
2. Yoon Du Jun of Highlight
Apparently, there was a good reason behind K-pop boy group Highlight's Yoon Du Jun's obsession over soccer.

Back in 2014, Yoon Du Jun was appointed as an ambassador of K League thanks to his enthusiasm for soccer.
