Whatever you do will be rapidly outdated by new technological developments. Whatever you do or say will quickly be known to everyone else. Whatever you do will be copied or bettered by your competitors. All services and products will get progressively cheaper, as increased competition reduces costs and increases efficiency bring prices and profits down to a minimum. Whatever you are offering, there will be a plethora of similar alternatives in the market place already.
Nobody can have more than one area of real expertise.
The solution you have to come up with is beyond yours, or anyone else's imagination. Whatever technology, programs, tools, methods and techniques you use will rapidly become unsuitable or irrelevant. Any final solution you come up with will have to be abandoned or radically altered within a very short period of time. Everyone is going to distrust you until you have built up a relationship of trust with them. Nothing is free, even if it seems to be.
