The closing speehc reminds me of something we say in italian: "We were young and with no problems. And we did not know it".
Quite nostalgic but still true as it always reminds me how much I complicate my life with troubles and losing time for people that are stealing energy.
I usually recall the latin poet that said "Hic et nunc", meaning "here and now" to help me stay focused in such situations
Just think about what we may have stressed about at school - and what we stress about now.
