Signing a big order, getting a promotion, winning the lottery - these joyous events not only soothe the weary soul that has struggled and fought, but they can also make one lose self-awareness and become overly arrogant, bringing trouble to one's future work and life. Perhaps because of the signing of a large order, you might overestimate your own abilities, turning confidence into arrogance; a job promotion might lead to self-inflation, making it difficult to handle relationships with colleagues and superiors, altering the way you conduct yourself in the world, and plunging you into an interpersonal crisis.
