"Taking on Challenges When Young is Valuable Even If You Fail"
The office desk of Lee Seung-woo (66), Co-CEO of LEESOL, who has walked the single path of technological entrepreneurship for 40 years, was packed with various components and research equipment. However, the item Lee selected as his absolute research "must-have" these days was none other than his smartphone. Lee said with a smile, "Components are getting smaller and smaller, but it's hard to see them well due to presbyopia. I conduct my research by taking pictures with my smartphone and zooming in on the photos."
