"I've studied now, to my regret,
Philosophy, Law, Medicine,
and, what is worst, Theology
from end to end with diligence.
Yet here I am, a wretched fool
and still no wiser than before"
"I well may know more than all those dullards,
those doctors, teachers, officials, and priests,
be unbothered by scruples or doubts,
and fear neither hell nor its devils
but I get no joy from anything, either,
know nothing that I think worthwhile"
~ Faust Part I (Goethe)
What brings happiness in life? Striving towards an unattainable ideal. Making progress towards that ideal. Slowly attaining god-like status, but never reaching it because once it's reached, life cease to have a meaning. Faust is miserable even though he knows much more than everyone else. You would think that knowledge will make him happy since he is a scholar. But he stopped making progress getting towards the god-like status. And more drastic measures must be taken to resume that..
I think one of the saddest things is to watch relationships break apart. Not just romantic relationships, but friendships as well. Friends that were once close become people you don't talk to any more. For no major reasons, just distance, time, new friends, new lifestyle etc. Some friends try harder than others to stay connected, but eventually everyone gives up and just make new friends from people around them. Too much effort otherwise. At the end of the day, what are u left with? Memories of great experiences. Strands of friendship that, maybe one day, will thicken and strengthen again. Or maybe it'll just be another name in the long list of friends on fb.
