Most people live unconsciously, without much self-awareness, bouncing around from one event to another and reacting based on whatever they feel at that particular moment. They automatically repeat the patterns and roles they learned in their families or wherever they grew up and never move past them. That's why you see so many adults who behave like children or are perpetually stuck in high school.
Living consciously is an entirely different approach to life. It means building up you self-awareness by getting to know yourself so well that you can deliberately feel, think, and behave positively. It means that you don't react to things based on your hurts, you actively choose an affirmative path. You're able to think not only about yourself, but about others and the greater good. You move past reacting to people and events and become a creator and promoter of beautiful things.
