A traumatic event doesn't doom us to suffer indefinitely. Instead, we can use it as a springboard to unleash our best qualities and lead happier lives.
— Jane McGonigal

We need the tonic of wildness...At the same time that we are earnest to explore and learn all things, we require that all things be mysterious and unexplorable, that land and sea be indefinitely wild, unsurveyed and unfathomed by us because unfathomable. We can never have enough of nature.
Henry David Thoreau indefinitely quote

Evolution is gaining the psychic zones of the world... life, being and ascent of consciousness, could not continue to advance indefinitely along its line without transforming itself in depth. The being who is the object of his own reflection, in consequence, of that very doubling back upon himself becomes in a flash able to raise himself to a new sphere.
— Pierre Teilhard de Chardin

At man's core there is a voice that wants him never to give in to fear. But if it is true that in general man cannot give in to fear, at the very least he postpones indefinitely the moment when he will have to confront himself with the object of his fear... when he will no longer have the assistance of reason as guaranteed by God, or when he will no longer have the assistance of God such as reason guaranteed. It is necessary to recoil, but it is necessary to leap, and perhaps one only recoils in order to leap better.
— Georges Bataille

Women are most fascinating between the ages of thirty-five and forty, after they have won a few races and know how to pace themselves. Since few women ever pass forty, maximum fascination can continue indefinitely.
— Christian Dior
