A teenager with progeria on how to be happy. His answer isn't about what's missing.
Berns speaks as a teenager with a rare, serious condition, so his optimism carries a credibility that advice from outsiders lacks.
In this TEDxMidAtlantic talk from 2013, Sam Berns, a teenager with progeria (a rare genetic condition that causes rapid aging), explains how he takes charge of his own happiness despite major obstacles. He sets out his personal philosophy: accept what you can't do and focus on what you can, surround yourself with people who matter to you, and keep moving forward.
