Vices and addictions are habits that we cannot control and, with time, they can harm us. Habits are not harmful; however, being unable to control them can be. You waste your money and time on things you dont need and, in the end, they create conflicts in your social relationships and affect your health as well. Any action such as watching T.V, playing video games, smoking, logging in to any kind of social network or drinking soda can be as dangerous and harmful as any addiction to drugs. All vices, addictions and bad habits have one thing in common: they are behaviors we cant control. This book presents a study about the nature found in vices and addictions and, with each of the 30 keys, looks forward to block the subconscious mechanisms that dominates your personality.
