In the yogik tradition there are four major goals of life, tarma, arta, gama and mokha. These include duty, wealth, pleasure, enlightenment. Enjoyment and fulfilment are two different things. And if you go down the hedonistic, nihilistic route, then you're going to shoot for enjoyment all the time, and you'll find an absence of fulfilment. i've seen this, like many man, many times.
