Given that I’m a happiness researcher, you might think I’d strive to help people eliminate unhappiness in their careers. But unhappiness actually serves a crucial function, signaling the need for change, prompting us to switch companies or fields, or even just motivating us to secretly update our resume at home (just in case). Unhappiness is what motivated me to jump from computer engineer to national CBS news anchor to now, happily, a positive psychology researcher.
