Переведи thomas edison tried two thousand different materials in search of a filament for the light bulb. when none worked satisfactorily, his assistant complained, “all our work is in vain. we have learned nothing.” edison replied very confidently, “oh, we have come a long way and we have learned a lot. we know that there are two thousand elements which we cannot use to make a good light bulb.” a lot of our behaviours, beliefs and emotions are driven by factors we are unaware of. if you’re in a happy, optimistic, ambitious mood, check the weather. sunny days make people happier and more helpful. in a taste test, you’re likely to have a strong preference for the first sample you taste – even if all of the samples are identical. the more often you see a person or an object, the more you’ll like it. and what we think of as memories, we tell ourselves a new story each time we recall an event.
