I like to think of myself as a social person. I enjoy getting coffee with friends and inviting people over for dinner. Yet when it comes to social media, I’m not quite as outgoing. I’m always unsure of what to post. Do people want to know that I nailed my last batch of cookies? How many pictures of my children do people care to see? And should I brag about every small win or bemoan each little setback? The answers to all those questions vary because people’s opinions differ.
