By quieting your mind and environment, your direction will be come clearer and more defined. With all of the noise and bustle of every day in being so busy, it is easy to become distracted. Silence it all, get rid of the television. You will be amazed at how much more productive you are without it. Also experimenting can help you find your purpose with dedication and work putting into it. I didn't find my true purpose until I explored myself and what I see myself doing until years later. Defining yourself is a whole new world once you see it in front of you.
