Time is a sort of river of passing events, and strong is its current; no sooner is a thing brought to sight than it is swept by and another takes its place, and this too will be swept away.
Everything has seasons, and we have to be able to recognize when something's time has passed and be able to move into the next season. Everything that is alive requires pruning as well, which is a great metaphor for endings. Henry Cloud
One of the illusions that we live by is that we can really know anybody else, and we're often surprised by traits in people that we thought we knew very well. The struggle to overcome loneliness, which is sort of our universal burden, leads us to leap to conclusions about who other people are. Thomas McGuane
