As humans we must change ourselves in everyday, months & years we live through. A living thing always evolves & changes over time. If we don't change, it means we are dead objects, not animated beings.
'I often sit and watch the leaves change colour and fall from the tree. To me, those leaves signify the constant change in our own lives and all the beautiful colours signify our own emotions. As the leaves, change and fall from the tree with such grace and gentleness, they're reminding us to be gentle with ourselves as this chapter ends and the next journey begins in our lives.'
(Changes, Personal and Spiritual Growth, Journeys, Final Chapters.)
The correct rate of speed in innovating changes in long-standing social customs has not yet been determined by even the most expert of the experts. Personally I am beginning to think there is more danger in lagging than in speeding up cultural change to keep pace with mechanical change.
(Mary Barnett Gilson (1877-?), U.S. factory personnel manager, economist, and educator. What's Past is Prologue, ch. 17 (1940).)
Such is the state of life, that none are happy but by the anticipation of change: the change itself is nothing; when we have made it, the next wish is to change again. The world is not yet exhausted; let me see something tomorrow which I never saw before.
(Samuel Johnson (1709-1784), British author, lexicographer. Nekayah, in The History of Rasselas, ch. 47 (1759).)
