The Factors that shape your life

The factors that shape your life?
You may have the standard answer "peers and parents," but really, there are SO many possibilities that shape your life, including your own, personal experience, government, school, advertising, etc. What are the other factors (other than peers and parents) that shape your life and how?

Music, Definitely shapes my life in so many ways. For one music can shape my mood depending on what Im listening to. For example, if Im listening to Lil Wayne, I feel like making money, therefor i only listen to him on payday. Another example would be that i listen to rage against the machine when im mad at something and feel like rebellion. I believe my life evolves around music, like music is the earth and im its moon.
Another thing that shapes my life is school, I don't talk to many people, however, I perceive what people do and how they react to certain situations. It can get really interesting too, how immature people can be, also how unreasonable. Some people will fight over anything even if its a compliment, i try not to be like one of those people. Its not peer pressure, peer pressure is their influence on your conscience and mind, this is strictly observation on how i should change so I wont be like certain peoples.
