Because it generally falls to me to make the esoteric observations that aren't worth actually discussing, may I raise issue with the penultimate paragraph here? Can we discuss the existentialist undercurrent here, or at least the lack of recognition thereof?
Specifically, a series of questions for you:
Do the "normal things in life which bring others happiness" seem like they are potentially happy-making for you?
Is understanding life a prerequisite for enjoying it?
Are the systems you reference ones of your own making, or pre-fabricated? What I mean is, can you expound upon the idea of "life system?"
I'm pretty sure that the problems you mention solving are the problems of young adulthood, about which (in an effort to make this post even more pretentious) I might suggest a recent NYT article which outlines some of them.
Also, I'm a little ashamed that this quasi-combative, probing, pretentious post is my first on v3. I guess that's what they call "setting the tone."
