Is existential angst self-obsession or legitimate angst? Is it feeling sorry for oneself or questioning the status quo of life and looking for more meaning? Why are some people more prone to it than others who don't seemed worried/in wonder of their role or destiny in life at all?
And then, if you get that far. How does one get out of it? Move past worrying about destiny and being and then to the next step of living with that awareness?

thanks! Good thinking folks!
