It is hard to close deals

For a salesman like me, everyday is hard day: i should keep on prospecting, keep on looking for potential buyers for our sea buckthorn oil, which is actually a very good one, high quality, reasonable price, why there are so many people argue that it is too high a price, they want it lower?

As the author of cold calling techniques Stephen Schiffman set it: every sales man will get 30 percent of the deal, no matter what business he is in, if he plays his part, he will get 30 percent of the total deal!

I wonder, is that so? or just my bad luck, or haven't located the right person through right ways. People say i should try google, yellow page, white pages, newspapers, that is what i have been doing, but where is the 30% of the deal?

I hope my first deal will come as soon as possible, why, because the deal itself still doesn't know what it means to me yet.
