The TED conference has featured several talks about creativity in recent years. Elizabeth Gilbert (Eat, Pray, Love) gave a little spiel about “creative genius” at this year’s conference. Before that, famed psychologist Mihaly Czikszentmihalyi spoke about the relationship between creativity and happiness. (It all boils down to “flow.”) And now we feature novelist Amy Tan (The Joy Luck Club), who locates the source of her own creativity, especially when writing, in her family history and big existential questions. The talk runs a good 24 minutes.
