Saying Yes and No

Again today I pulled the "Hell No!" card, The Seven of Wands. As I said before, I see this card as a card of setting boundaries, drawing lines in the sand. But, what about setting boundaries with the hardest person to set boundaries with?
In the 1980s my mother smoked herself to death. She was on oxygen and smoking at the same time. She literally could have blown the house up. We human animals think we are so smart yet we seem to have a death wish sometimes. We abuse substances, drive dangerously and generally wilfully engage in dangerous practices individually and collectively. We seem to have a hard time telling the difference between what we should say no to and what we should say yes to. How do we draw the line between the two?
Sometimes we have to look inside.That's why I am invoking The Moon. How do you know the difference between that which you should deny yourself and that which you should indulge in? In The Charge of The Star Goddess Starhawk says, "For if that which you seek you find not within yourself, You will never find it without." She also says. "Let My worship be in the heart that rejoices, For behold — all acts of love and pleasure are My rituals."
When I want the answer to these questions, what should I allow or deny myself, I know where to look.
