In these days you will find yourself away from home, working in a place of strangers. Your evening and night will be spent alone in an anonymous house and you will not find any diversion. My advice is to make like old Japanese fishers in 1800, they were used to keep under the pillow an erotic (or pornographic) image. Most of these images were drawn by painters and represented naked geishas and a tentacular partner, an octopus or something similarly fantastic. Use your fantasy to find a piece of eroticism in your solitude.
