“I’m not sure exactly when it starts. And even more of a question for me is whether or not it is a genetically predisposed trait or something that we learn at an early age. Either way, it is a trait that is sometimes worthwhile and maybe even useful, but often counterproductive and problematic. I refer here to the “art of worrying,” and yes, some people are so good at it that it has become an art form for them.”—Lyle R. Hill
