Everything that has a beginning has an ending.
Make your peace with that and all will be well
Jack Kornfield, The Buddha’s Little Instruction Book

The art of living…is neither careless drifting on the one hand nor fearful clinging to the past….on the other. It consists in being sensitive to each moment, in regarding it as being utterly new and unique, in having the mind open and fully receptive
Alan Watts, The Wisdom of Insecurity
Contrary to most professional opinion, a gnawing dissatisfaction with life is not a sign of “mental illness,” nor an indication of poor social adjustment, nor a character disorder. For concealed within this basic unhappiness with life and existence is the embryo of a growing intelligence, a special intelligence usually buried under the immense weight of social shams. A person who is beginning to sense the suffering of life is, at the same time, beginning to awaken to deeper realities, truer realities. For suffering smashes to pieces the complacency of our normal fictions about reality and forces us to become alive in a special sense – to see carefully, to feel deeply, to touch ourselves and our worlds in ways we have heretofore avoided.
