“You’re a point (Y). Off in the distance somewhere is a line that represents your death (D). Two other lines (E1, E2) - the extremes of what you can do with your life - radiate at an angle (A) from Y, eventually crossing D.” From a very old post (early 2000) I just stumbled across at kottke.org (post by guest editor Greg Knauss) - this might be on-topic or off-topic depending on your situation, but there’s something here that really makes my mind whirr.
