Time is not a line, but a series of now-points.
The passing moment is all that we can be sure of; it is only common sense to extract its utmost value from it; the future will one day be the present and will seem as unimportant as the present does now.
W. Somerset Maugham
To realize the unimportance of time is the gate of wisdom.
What then is time? If no one asks me, I know what it is. If I wish to explain it to him who asks, I do not know.
Life is all memory except for the one present moment that goes by so quick you can hardly catch it going.
