I read an article about people who generally made small talk with strangers vs. those who didn’t. Most people would think that talking with strangers is often talking about things like the weather. It turns out, however, that those who engaged in the conversation generally enjoyed it and felt it added to their life.
So stop looking at those shoes and say hi to someone today! Chat them up and see what the world has to offer of interest.
It could be doubly beneficial.. the conversation may brighten their day as well.
