Too Long; Didn't Read
An idea is just a point in a coordinate system; project work requires a vector. The main task is to move from place to place in the right direction and keep moving making changes. It is important that the market and demand for a similar product or service already exist. Being the first on the market does not mean that you will lead it, the market doesn't work like that. It takes long to change people's habits and it takes even longer to develop a new market. Investment is not always good or bad, it all depends on the particular situation.
