But life also happens anyways. For me, a lot of what constitutes "staring into the abyss" is accepting that neither the original plan nor my alternate wish worked out as expected - despite the best laid plans - because almost nothing ever does. It's not just considering all the implications of a decision but accepting that things just work out differently than you hoped.
[edit] I guess I mean that accepting the inevitability of previous disappointments is as much or more a part of grappling with the abyss as is considering the future.
