A more interesting question than “How are you?”
I can't take credit for this brilliant idea - credit is due to Jen Gitomer - but what if instead of asking someone 'how are you?' or 'how's your day?' you ask that someone to tell you the highlight of their day so far. You can frame this a couple of different ways: the highlight, the funniest, the most interesting, the biggest aha! moment.
Whatever you choose, it will be, by far, more interesting, more real, more connection-inspiring, more human.
