Depends on what your definition of "enjoying your life" is. And then certain habits such as binge drinking are largely promoted as enjoyable via peer pressure/peer brainwashing. I mean, we have only so much sensitivity to alcohol, and so many GABA receptors to saturate, it's not like people would want to drink as much if they were on their own. And, in the end, a hedonistically-driven life is only superficially rewarding. It also shows lack of goals, focus, potential for impact.
