When no one is looking and you're not trying, what shows on your face?
We have a default setting, an arrangement of muscles that gives our mouth and eyes a look. Some have, as a friend of mine says, "resting bitchy face." People rely so much on reading faces that even though you might not intend it, people are making an assumption about your mood and your approachability.
Interesting question: What's the 'resting face' of your brand, your business, your website? In the ordinary course of business, when no one is really focused on trying, what do your emails, signage and word choices telegraph about you?
Over time, many businesses devolve into an efficient yet foreboding default. It takes effort to move uphill, to put a smile into your voice and your typical interactions.
What could be worth more effort than that, though?
