Therefore , Empowerment Self Defense starts with the principle Think , dedicated to prevention and awareness. Do you listen to your intuition? Do you pay attention to your environment? Avoid wearing earphones at night, which block out noises from the environment. Have you mapped your way home? Is there an evening store opened late? Is your street well lit, and does your building have cameras? When in a bar, keep an eye on your drink, know if there are any cameras, and if alone, stay close to a bartender and make yourself known to a security guy.
