I do have to say that's part of it. It gradually started when I was cycling often on my days off. I noticed other cyclists would usually nod or wave when they saw me. I felt a sense of community when they did that. Then I started doing it in return.

After signing up for Happify.com I started doing some of the activities they suggested and smiling at a stranger was one, that also helped push me into making it a habit. My work also helped some, although it doesn't require me to look people in the eye.

I also feel it helps me to feel like I can trust others more when I do it.
