later you will be running after it

Nadya, pink-cheeked, happy, her eyes shining with tears in expectation of something extraordinary, circled in the dance, her white dress billowing and showing glimpses of her slim, pretty legs in their flesh-tinted stockings. Varya, thoroughly contented, took Podgorin by the arm and said to him under her breath with significant expression: "Misha, don't run away from your happiness. Take it while it offers itself to you freely, later you will be running after it, but you won't overtake it."
- Anton Chekov, "A Visit to Friends"
