Best chance you probably have is to look for signs of satanism anywhere.
If not, try to find someone who is spiritually openminded. Then show him satanism. My GF is spiritually open minded, but she doesn't extremely interest herself in Satanism. Which is okay, because she lets me do my thing and her thing doesn't clash with my thing so it's a good situation.
Or ask a demon to guide you to what is good for you.
He'll know what you mean.
