He managed to acquire two PhDs and climbed to the top 1% in terms of possessions and position. Nonetheless, he failed to achieve happiness along the way. In 3D of Happiness, Necati shares his journey of having, doing, and being which turned out to be a cycle of deprivation, emulation, accomplishment, and disappointment.
