I believe responsibility starts with taking care of ourselves.
In a nutshell: “taking care of ourselves today, in a way that will allow us to take care for ourselves in the future too.”
(Such as, if I were to betray my friends today, it ‘d be left lonely tomorrow.)
Yet, it’s not about consequences. It’s about growth: to take care of ourselves, means to realise that “being”, and “becoming” are two entirely different states of possibility.
