What we do doesn't define us, it's who we are that defines what we do.
It sounds the same, but if you think about it, we are much quicker usually to define a person and their character by their actions, rather than understand that the actions are driven by the person. If we did, we could be more empathic, give deeds less value than being the definers of an entire person. People are more dynamic and complicated than that.
It's so hard! I struggle with this constantly.
I've been thinking the opposite for a while, but nowadays it makes sense the other way around. Your deeds will always be the result of...you. Feeling and thinking, experiencing, going about life. Those deeds are the ultimate manifestations of who we are, but only at moments in time, and not forever. Every day you are slightly different, and so your deeds might be different too - this becomes most clear to me when I dance, with myself or with others.
