A decent percentage of people with Schizophrenia say that sometimes the voices provide company, and the hallucinations are sometimes entertaining. But, almost all say its impossible to hold a job with voices in your head, and while they (the voices) may try to "help" you with their comments, they often tell you to do things the wrong way. Like you boss says " clean the kitchen and take out the garbage" and the voices tell you to do it reverse. The voices may be trying to help you, but its going to get you fired.
I used to have a similar problem when I was younger, voices would give me orders and say if I didn't comply me, family or friends would be injured. The orders would be sometimes be contradictory to what I was told to do in school, by my parents etc. and other times be stupid little things such as touching/picking up an object and if I didn't do it there would always be a awkward feeling down my spine. This made me appear somewhat obsessive compulsive. I also used to and still at times do believe parents or authority figures are attempting to read my mind, and thus try my best to watch what I think around certain people.
Who knows if its actual schizophrenia, I researched it a couple years ago and found it is very rare and occurs in 1% of the population, may be genetic and is very rare to have at an early age. Unless of course it is under-reported, and I do believe most everyone has heard 'voices' at some point in their life.
Eventually I learned I could drone them out, or simply laugh at them. It can be very beneficial as to help you see things for different perspectives, though to others it can make your statements look seemingly paradoxical. I also enjoy my dislike for authority, it really helps you question what you're told...even the things you tell yourself. When I learned about Timothy Leary, Abbie Hoffman and Bill Hicks it was like I found a part of myself.
