Sometimes actions are part of a distinct chain reaction:
A charity coordinator launches a campaign to solicit donations, your friend finds this campaign compelling and, in addition to donating, goes out of her way to tell you about it. You donate and share the campaign as well. Suffice it to say, the campaign succeeded in part because you and your friend chose to participate.
Other times, actions are responsible for the chain reaction:
One employee makes a point to ask all of her teammates first thing in the morning how they’re doing. Touched by this gesture, a large portion of her teammates then go out of their way to ask other colleagues in their meetings how they’re doing. The gesture continues to create ripples for the rest of the day and the result — one of them at least — is a collective smile on the face of an organization.
Realizing that you can be a part of or the beginning of a movement isn’t the most enticing takeaway though…
It’s realizing that you, at any point, can be a force of good by choosing to join a movement or, better yet, recognizing and acting on the opportunity to graciously tip the first domino.
