Having a positive attitude about your "health" starts with having a positive attitude about "yourself."
In my book "Eating to Die: Changing African American Attitudes About Health," I discuss how attitude affects our behavior in Chapter 5, "Attitude shapes Behavior."
Our attitude is the way we think, feel, or act that shows our opinion about something. Whatever attitude you have about your health, good or bad, is reflected in how well you take care of yourself.
When you have a positive attitude about yourself you are more likely to make healthy lifestyle choices, think of your life as valuable, and feel that as a human being you are worthy of the best.
When you have a negative attitude about yourself, consciously or subconsciously, you are not likely to value your life as something that is precious and deserving of care. As such, circumstances relevant to quality of life and making healthy lifestyle choices will not be at the top of your priority list.
