Change & Aging.
They’re the only permanent things.
Just a timely reminder. If you're always battling against getting older, you're always going to be unhappy, because it will happen anyhow. It’s one of the most beautiful things. Grey hair. Skin lined with hardship. Tiny steps to remind us that we finally have to slow down. :-)
Quoting Mitch Albom in his Tuesdays With Morrie,
"Aging is not just decay... It's growth."
