Often my ideas have something to do with an inefficiency I've seen, or a nagging problem that doesn't seem to get the attention that it deserves.<p>Watch lightning in slow motion sometime. Many times before I come up with an idea, my mind is racing and seems to send out branching tendrils through resources, problems, techniques, news, people, previous ideas, etc. Like step-leaders in lightning, many alternate paths and branches are evaluated and activated. As this network expands, a solid connection forms between a problem and a solution, and BANG! An idea forms. Sometimes with many important details baked in.<p>I focus in on this active path, and debate the merits and ramifications and potential pitfalls. Sometimes this idea is valuable and new. Many of my ideas have nothing that would connect them to anything I've worked on before.<p>Often these Ideas will get lost if I do not write them down, so I always endeavor to do that. Reading through these old ideas is a good way to re-activate these pathways of invention again and generate new ideas.
