Y.O.L.O. you only live once, is a short-form phrase that are often used on the net recently.

some may say that since u only live once, you might as well juz enjoy life by living at the present while forget abt the past and dont think about the future.

however the past are the main element that defines who u r.

And although sometimes thinking about the future brings fear
but only to counter it that will make life more challenging hence more worth living

:D
