In Ancient Greece, when the philosopher Socrates was asked to sum up what all philosophical commandments could be reduced to, he replied: `Know yourself'. Self-knowledge matters so much because it is only on the basis of an accurate sense of who we are that we can make reliable decisions - particularly around love and work. This book takes us on a journey into our deepest, most elusive selves and arms us with a set of tools to understand our characters properly. We come away with a newly clarified sense of who we are, what we need to watch out for when making decisions, and what our priorities and potential might be.
