Daily regime

Is it us as the collective human condition, that we suffer monotonous lifestyles, like the ideology of Jean Paul Sartre, each note in a piece of music awaits their penultimate note and then dies, whereby another note replaces the previous. Even though the death is insignificant, it gives the listener an insight into the structure of the notes. Shouldn't we all be conspicuous of these insignificant details. Or should we be blind to our own expression?
