It's not a bad thing, but it's certainly not all that progressive or helpful in most social situations, in my opinion. It's a fairly antagonistic approach to bring to the table of thoughts required to provoke viable and working solutions.
All the greatest and most important problems of life are fundamentally unsolvable...[they are] not solved logically in [their] own terms but fade when confronted with a new and stronger life urge. Carl Jung
I get like that sometimes too.. I just think fatalistically (is that a woooord????) anyways.. so I don't get disappointed, I prepare myself for the worst.. but.. it's pointless.. because with such a mind set you create negative things to happen anyways.. while thinking positively does the opposite.. but yea sometimes I just can't do it and get negative because.. hmm life sucks, sometimes.
