Niels- The author/blogger Mark Manson wrote about this in his best selling book “The Subtle Art of Not Giving a F***.” He talked about how an elderly woman in line might be totally focused on her coupons because that’s all she has left to give a f*** about in life. I read this after I wrote my article and it made me realize that some people complain about small things because there’s not much left in their lives. Thanks for reading and your email.
