You are saying your environment controls you and I am saying the opposite. You control your environment. These concepts are not the same thing.
You are who you are because of your EXPERIENCES in life NOT your ENVIRONMENT. You choose to be a Shepard or the sheep. It's your choice.
What is your definition of environment? http://en.wikipedia.org/wiki/Environment
The natural environment, commonly referred to simply as the environment, is a terminology that is comprised of all living and non-living things that occur naturally on Earth or some region thereof.
The social environment (context), also known as the milieu, is the identical or similar social positions and social roles as a whole that influence the individuals of a group. The social environment of an individual is the culture that he or she was educated and/or lives in, and the people and institutions with whom the person interacts. A given social environment is likely to create a feeling of solidarity amongst its members, who are more likely to keep together, trust and help one another. Members of the same social environment will often think in similar styles and patterns even when their conclusions differ.
