With regards to questioning, it's just part of the business' journey towards taking its first step at the ladder of success. Without questioning, the business will not grow and will not become more tough against possible problems that may occur when it's already taking its steps on the ladder of success.
There is nothing a matter about questioning in making a business, of course it is also important that your business is in accordance with the wishes and demands of many people, but asking too many questions and never starting a business is wrong dude? too long in the process will not make you get progress, just try!
Of course, when you are in the first step in business you need to ask more information regarding on what business that fit to have either in any places. I think there's nothing wrong with asking a question for me, at least you are aware if there is negative feedback from the answer that you want to know, then, you know how to handle with it. Starting a new business is not a kind of joke, you put a risk your money as a capital, be researchful before engaging into a business.
