Phil Hansen suffered a career-threatening injury to his hand. Nerve damage caused his hand to shake uncontrollably. Most professions could deal with it. But as an artist, where a steady hand seems essential, it all but doomed Phil's career. That was until a neurologist suggested he “embrace the shake.” That piece of advice "tweaked Hansen’s point of view and sent him on a quest to invent different approaches to making art by embracing personal and universal limitations." Watch his story on TED. I watched it and found three principles and four techniques of the innovation method, Systematic Inventive Thinking.
