[Amokrane]

FWIW, I grew up in a third world country, waking up everyday fearing that I or someone I care about will die in a bomb attack (search for Algerian Civil War: http://en.wikipedia.org/wiki/Algerian_Civil_War) and having all sort of daily issues (no water for a week, no electricity for days, etc.), and I can tell you this for sure: this didn't prevent us from wanting a life that's above average, from pursuing happiness and from questioning whether we loved what we were doing or not.

Also, I am not sure where you are reading that you should be solitary or not have any family. I take care of my parents, a depressed brother who threatens to suicide every now and then, I am married and would love to have children. What's wrong with having that and aspiring to work on something that you find enjoyable instead of settling on a boring job?
