Emmet Fox said: “You are not happy because you are well. You are well because you are happy. You are not depressed because trouble has come to you, but trouble has come to you because you are depressed. You can change your thoughts and feelings, and then the outer things will come to correspond, and indeed there is no other way of working”. A photographic investigator’s job consists, partly, in proving, photographically, the truth of what she believes in. Like the quote from Emmet Fox, mentioned above.
