It seems that you can have a goal without any clear way to achieve it. If you’re in pain and don’t know how to fix that (short of, presumably, suicide), you can still have the goal “get out of pain”. I think I could legitimately be said to have the goal “live forever”, even though I don’t know how to do that. Are you saying it’s bad to have goals that you don’t know how to achieve?

My comment mentioned that the pain keeps you from thinking.
So, if the goal is something that you:
a) don’t know how to achieve
b) are unlikely to learn how to achieve
c) have trouble thinking about anything due to the existence of it,
d) don’t even agree with the goal,
e) your health does not suffer from not pursuing the goal
Then yes, taken together, it’s obvious why goals meeting a-e are bad.
