When Albert Einstein wasn’t busy debunking misconceptions about the fundamental nature of time and space, he had a few interesting things to say about human nature. “The definition of insanity is doing the same thing over and over and expecting different results,” for example, is one of his most well-known utterances and probably one of the more intuitively comprehensible ones, verging even on common sense. Why, then, do so many of us struggle to apply it to our professional lives? Why, according to a recent Gallup poll, do 85% of us turn up every day to jobs that we hate? Presumably, it’s because we don’t have any choice. Actually… no.
