Attachment theory is important because it's going to help you to understand your own relationships. Information is power and recognizing yourself in one of these attachment styles could really improve your future. If your parenting was unpredictable in childhood you might develop into an anxious attacher or also called angry & ambivalent; a clutching to get what you want. If you were ignored early in life you become an avoider or distancer because they learned they have to depend on themselves. The best attachers are secure, and so they don't react so impulsively.
