A beautiful card from Finland comes with good advice:
"It took a long time to understand how how easy it is to improve the world: to remember something and forget something, to smile like a child, and not to be afraid to love." - Tommy Tabermann[corrected after soubriquet's comment, thank you, soubriquet]
The original in Finnish is a poem. Tommy Tabermann was known, among other things, for writing love poetry. He died last year at the age of 62.
