In business, the potential problem with focusing on too narrow a niche is that technology and the world we live in today move so fast that your niche can become irrelevant so quickly. While it is important to focus on one's core tasks and goals, we also need to be aware of the opportunities and trends in the surrounding environment, in order to make the best decisions and adapt to changes. It’s our metaphorical peripheral vision that can help us identify new market trends, changes in customer needs, or even new technologies that can help our business grow and succeed.
While chasing every new idea can be counterproductive, it seems that training our peripherals is now more important than ever.
