Bosses are always right?

Don't lead me to no way. Yes i may not be very good in technical but it doesn't mean i do not know how to sell it. Really feel demotivated when ppl change their thought so frequent. I need to know exactly my direction so i can 'FOCUS' to what i am doing now. Its been six months i have been doing all the paper work and now i still end up doing paper work after getting confirmation. They said i am allowed to go out to meet up people but what is the point when people are interested in my company product and end up i can't much about it because i am not allowed to negotiate the price as my job scope now is still more to sales support rather than sales engineer.
