"A common theme prompts again at me/
I wonder what could the answer be/
Is it forwards I'm going or back/
Or is it moving wallpaper I'm looking at?"
I like the question of the validity of time as a frame of reference, but it becomes especially interesting if you shift perspective on your own life (in that kind of way you can shift your eye's focus from the close to the far away and for a second mothing makes any sense to your brain). Cease from looking at it as a major linear event interspersed with minor day-to-day diversions of attention. Think about your life as those diversions, with some moving wallpaper in the background. It's just as valid, if you accept that, for most people, most of life is filled with small diversions.
I tell you, it's one certain way to escape the self-indulgent attitude of the tragedian, or the socially-responsible, or the ambitious. At least for the length of time it takes your eyes to re-focus.
