When we react, we respond impulsively. We might experience a momentary catharsis, but also, in all likelihood, we make the situation worse.
We respond from our generosity. We perceptively consider what is needed and can shepherd a positive outcome.
With both reactions and responses, though, the process started with someone or something outside of ourselves. The alternative is to initiate.
This takes courage, to begin something new. With initiative, courage, and endurance, though, we can do the important things. We can weave people together to serve the common good.
