YOLO is a philosophy? Hahah. Maybe for the Tumblr/FB teens who don't have anything better to do than to come up with pseudo-intellectual BS. If you really really think about it, sooner or later you'll realize how stupid it is.
The best way to counter that and all other pop-culture crap is to embrace Islam wholeheartedly and accept all of its doctrines, in this case the one about the life after death. You only live twice. First time, in this life, to take a test and second time, in the afterlife, to get your reward/punishment. That should be your motivation. Because if you live by YOLO you'll do a lot of forbidden stuff and once you come before Him there's no more time for regrets, no excuses, only you and your deeds.
