With no direction you are lost.
With no light you are in the dark.
You will not be fulfilled unless you are living your dream. You will be easily swayed and manipulated unless you have principles to live by and guide you.
The quality of your life is based of the quality of decision you make. The clearer you are about what you want the easier it will be to make these decisions.
Understand how the world works and set goals so high that it pulls you to accomplish them.
