wow I got a completely different idea from this question...
I mean along the lines of Albert Camus and Sartre... so I mean the essential Existentialist question is "what is point? Why bother living when everything is random, you have complete control of you destiny, but that is not a gift like Rousseau believed, but a terrible, terrible burden" Which I tend to agree with. I hate making decisions. lol
but in all seriousness, my biggest question is "what is my purpose?" and I know the answer and that is "I don't have one" coping:" apathetic acceptance that I am no more significant than a mosquito. However, that said, I may not have a purpose, but I can fool myself into thinking I do have one, it may be my job, or college, or my boyfriend, or helping an old lady across the street, those give me a purpose, at least something that ressembles a purpose for a short moment in time.
