Look at all the categories of goods you have available. You can have virtually any furniture, clothes, jewelery, stationary or mobile electronics, craft and hobby tools, transportation, food, books, or services of various sorts. You can fill up your leisure with so many possible activities that it may become very hard to find something you really enjoy, something that hits the spot and allows you to stop searching. And now image you have a new product or service. This product will need to compete for attention of your potential customers with everything else that is so sexy already and what they already know. How do you get it through to their awareness? You can also try to make something actually useful. Something that is needed for something, like cheaper technology for producing plastics, or to mine titanium as efficiently as iron is now, or allows to launch medium-scale production in a garage with $10k worth of equipment. This seems to be much easier way than to compete with luxury distractions we have. But, of course, you need to have an executable idea for a real need out there.
