It's just an info-graphic. A reminder at how important it is to have weekly goals. The squares toggle, so I could mark the current week, or a short period. I think it's pretty awesome you drew a smiley face :-)
I think these things are kind of grim. Living life without considering its length as a motivation to do things is perfectly fine.
Ever since the 60s, epiphanies and ideas like this are fads, fashion statements. How did George Romero say it? Something like "it was the 60s, everyone had something to say." The 60s never ended, people keep thinking they have something to say, and since nobody's listening to them on Twitter and Facebook anymore, they're just getting more creative.
People will always have something to say.
That's the nature of being thinking beings.
Say someone decides to mark all the significant events in his life. And notices that it's beginning to spell words.. maybe a neat story?
