A well-balanced life is most often the result of a combination of numerous little factors in a day to day existence of an individual. This balance is maintained by being aware in every facet of the person's life. Awareness, in this case, is a result of being highly sensitive to your sense of peace and contentment. This balance is not lost in one fell swoop, but rather in a series of small, interconnected actions, reactions or inactions that lead to a loss in your inner calmness.
As humans, the things that make us happy and content are as different and diverse as we are. Living a well-balanced life is a result of keeping stock at every point in your life and learning to do things that would, not only at present but in the long haul make your life fuller and more ordered. These actions and decisions cannot be made for you, and cannot be copied from that of friends or family as they are different individuals who have their races to run and their paths to go.
To fully understand your race and your path to self-fulfillment and a well-balanced existence, you must develop a heightened awareness and understanding of yourself and your priorities. Your self-awareness will help you to prioritize appropriately the things that are most important to you and learn to take stock of the balance of these factor in your life at every point.

Some people are capable of being the same kind of person, with basically the same wants and needs through most of their life, but such people are few and might even have to alter these requirements to fit their respective environs at each stage of life.
Deep awareness helps us to keep track of the changes and requirements in the various stages of our existence to stay ahead of these changes.
