Impermanence...

Don't make any human being the center of your world, don't ever completely rely on a human soul...'cuz every other human on this planet is as unpredictable and as helpless as you are...

Seasons change, new buds bloom and old leaves wither, ice melts and clouds rain down...dawns break and night somehow supersedes it all...

Nothing's permanent, you see? Everything's temporary...and so is life...
