How the CEO of cybersecurity company Trend Micro confronted her fear of butterflies

Lepidopterophobia, or the phobia of butterflies and moths, is something that bothers Eva Chen, CEO of cybersecurity company Trend Micro. 

Overcoming her fear has helped Chen navigate the world of business, especially when she has a tough decision to make.

"When I was little, I was scared of butterflies. I don't know why. Until now, I still don't know why I think butterflies look very strange," Chen shared with CNBC's My Biggest Lessons. 

But when Chen took the helm of Trend Micro, she decided to confront her fear of butterflies by keeping a taxidermy of the insects. 

"I put [the preserved butterflies] in my room, everywhere. I forced myself to look at the butterflies every day. And I started to wear everything that is butterfly-shaped," Chen said.

"Once I did that, I overcame my fear, then I believed in myself," she added. 

Now, when Chen has a difficult decision to make, or a tough interview lined up, she wears her butterfly earrings to remind herself of overcoming her fears. 

"I touch my butterfly [earrings] and say, I can do it, I can overcome my fear," she said.
