When it's all said and done it want matter, it'll only matter in that time. So
in that time enjoy the existence of that time before that existence is blown
away like a candle in the wind. No wishes comes true setting around waiting
for it, life is about living. Make it  what you want. What you every do, be
happy while doing it, cause when the end comes, it'll be bitter sweet. Some
receive this end more bitter than sweet, other a little more sweet than
better; all in all it will not be what you want, so grasps what you want while
you still can before time rob you of your strength. Enjoy this freedom before
death claim it. Enjoy life my friend. Only one you get, and only one you will
ever had.
