Don’t worry about being your brother or sister’s keeper until you master keeping yourself. A pretty good rule of thumb is, “you’ll likely never master keeping yourself. “I want to help” is a statement of “I know what is best for you,” and while it looks like you may be helping, you are serving your own “wants,” whose ultimate aim is “getting” something you want. Do you see?
Be kind, gentle, and humble, and offer others only love, unnamed, and unparticularized. That is, what “keeps” you, and it will be enough for others, too.
