“Do not spoil what you have by desiring what you have not; remember that what you now have was once among the things you only hoped for.”
― Epicurus

“As if you could kill time without injuring eternity.”
― Henry David Thoreau, Walden or, Life in the Woods

“True happiness is to enjoy the present, without anxious dependence upon the future, not to amuse ourselves with either hopes or fears but to rest satisfied with what we have, which is sufficient, for he that is so wants nothing. The greatest blessings of mankind are within us and within our reach. A wise man is content with his lot, whatever it may be, without wishing for what he has not.”
― Seneca

“Time isn’t precious at all, because it is an illusion. What you perceive as precious is not time but the one point that is out of time: the Now. That is precious indeed. The more you are focused on time—past and future—the more you miss the Now, the most precious thing there is.”
― Eckhart Tolle, The Power of Now: A Guide to Spiritual Enlightenment
