Apart from television characters... everyone does it eventually and in my opinion it is a major problem with society as we know it. It is something that needs to be stamped out. It is because of this conformity that the world is in such a mind-boggling state. There is only one way to have true freedom in life and that is to make your own choices, on your own terms, for you and only you. Now I can hear you saying, "I do make my own choices..." But ask yourself...do you really? Yeah, yeah you're still saying YES. But I'm gonna rock your world a bit— you see, when you buy a product because you've seen it on TV or if you go to a night club or a restaurant or movie because a friend told you it was spectacular... then, in essence, you are conforming. If you read a story on the web and just blindly believe what most of the articles say (and trust me 70 to 80% of the world does just that), then you are conforming. If you feel that everything has to be ordered, you are merely conforming.
We live in a world controlled by nature. Humans are NOT better then nature. We seem to think we are at any given moment, primarily because we are by our very nature, ego-driven, but we aren't. Things are sometimes chaotic for a reason. It balances out the rest of the perpetual marketing crap we get to swallow each and every day. The only way to do things and live life in a free and uplifting manner is... well, simply by drawing your own conclusions and forming your own opinions— based on your own research. Instead of just accepting things people say, do a little research into the topic. If it's a news story, read all of the sources of that story you can get your hands on and make up your own mind as to what appears to be the most logical of events which could have occurred.
Buy products because you have had experience with them and you know for a fact that they work. Don't allow yourself to be brainwashed by clever ad campaigns put together by some 21 year-old in the MTV fashion of the week clothing and a reversible baseball cap. Do what you believe in. Trust in yourself and what your mind and your instincts tell you. Listen to that "inner voice". It's tough... even for me, but we have to start somewhere.
