I think that by now, everybody knows what YOLO mean. This scary idea of having only one life started with a gerenation who wanted to enjoy they life but fast became a joke. Sadly, Yolo is now an excuse for stupid people to do stupid things.
So this " You Only Live Once" turned into " You Only Live Once, Let do stupid things"
The meaning of Yolo is now empty, but hey, you can buy this awesome tshirt. Yolo is just a trend, nothing more.
before this YOLO fashion, we had an other phrase, something that i found way more powerful : Carpe Diem
Seize the day.
SEIZE THE DAY.
This is an other way of living. Nothing to do with YOLO.
In the end, either you believe in YOLO or in Carpe Diem, the most important thing is to enjoy your life. Love it. Make something good out of it.
You only live once so seize the day and be happy.
See ya later <3
