"No te tomes la vida muy en serio, despues de todo no saldras vivo de ella" which translates to "Don't take life too seriously after all you won't come out of it alive" though for some reason I wrote it like this on my profile "Don't take life too seriously since you know, you won't come out of it alive anyway"
It's something one of my mother's friends told me after I came home with all bruised from fighting at school because someone called me a coward, 3rd fight I had gotten into that week, I adopted the phrase for myself later on mostly to confuse my friend, it's meant to be funny because it's the kind of phrase that doesn't fit me at all, after all I almost never smile and according to my friend the day that I laugh it's the day reality will shatter, it's also sarcastic because I tend to say it in the most serious way possible while I look like I'm half dead, but it's also meant to represent how I have no regard for my own well being, often doing stupid stuff like fighting 3 muggers at the same time all by myself, which is really stupid considering I have never won a fight, ever, it sort of matches my view of life in a bizarre way, because it's both optimistic and pessimistic at the same time, and yes I have put way too much thought into it, kinda funny since as I said it was originally just meant to be funny because of my deadpan way of speaking and my incapacity to show much emotion when I speak, but it oddly started to fit really well, at least in my head anyway.
