Suppose you have been working on the solution to a challenging technological problem for many years. Let's also suppose that you have been paying attention to whatever else you have encountered that might be related to the problem. In that case, chances are that creative solutions to the problem could suddenly pop up in your mind when you are relaxed. Such "eureka moments" (when great insights lead to discovery or invention) often take place at unexpected times. To enhance spontaneous creativity, therefore, one must pay attention to the things that could potentially lead to valuable outcomes. This does not mean that you must narrow down your interest to one specific topic. On the contrary, breadth of experience is the key to creativity. If your experience is limited to a narrow range of topics, then the scope of your imagination will likewise be narrow, which would be harmful to creativity.
