There are many rookie mistakes that can kill off a young company. The marketing survey of 1 has led many people off a cliff, based upon the whims of a single customer. Long ago, I was dissuaded of the thought that I could ever be the common man. I don't know what he wants, and can never guess where he's going to go.

Thus, because I can't figure it out, I might as well ask him. Even a lie will have some truth in it. And any answer I get will be closer than one I make up myself.

Don't try to get the item "perfect" before going out into the marketplace. Don't depend on guidance from just one source (yourself or anyone else). Go out there, ask stupid questions. Even in one person tells you something wrong, that false statement will get washed out
