Input: [header] How to substitute pornography [title] Find fun activities. [step] Instead of temporary pleasure that you may feel guilty about later, invest in your happiness. If you don't have any work to do, then start doing what gives you happiness (porn gives pleasure, not happiness). <sep> (A) Meetup.com provides fun and downloadable activities. [substeps] If you love reading, then find something reading. (B) Create activities that take your mind off the sugar and waste accumulated in the body. [substeps] For example, you might take your cat for walks every sunday morning, play charades, take a walk in your neighborhood, or watch a funny show on youtube. (C) Instead of spending time watching pornography as it is relaxing and educational, use it for fun and discovering how the world works. Take that step and visit your local library and check out reviews. (D) Find activities that take up a large chunk of time that will allow you to get out of the house or at least be occupied for a substantial amount of time. [substeps] Invest in some hobbies you find enjoyable, especially social hobbies that allow you to make friends and have fun.
