Have been reading an excellent business book: Double Double by Cameron Herold. He gives great advice about a number of things, including keeping a clear boundary between work and family time. He used vivid imagery to humorously describe how checking your iphone while supposedly spending time with your family basically dulls and desensitizes everything and you end up not doing anything well. OK, he said that checking your iphone during family time is like wearing a big body condom all day long. Effectively gets his point across.
