It should be simple to make up a few fortunes - just tell people good things will happen to them and to avoid talking to black cats. But you're not projecting the right kind of confidence, and people just aren't paying up.
This fortune-telling lark is simple. Peer at grubby palms and deal a few cards; [...] it doesn't matter what you actually say. Tell people that they will meet handsome devils or inherit money and they'll pay you handsomely in secrets and pearls.
