This one chance

You have heard it all before, but have you ever really embraced it's meaning? We only got this one chance to live. That is it only one shot at this life. So can someone please tell me why the hell we are not all living for the moment? We should be living each day as if it were our last. What if you only get that one chance wouldn't you want to take it then? What if there was no tomorrow? There is no reset button to life; there may be no second chance. So why take that chance at all?
Do not let the moments of your life pass you by. You do not want to come to regret the choices you never allowed yourself to make later in life. All I am saying is live for the moment. Take a chance and wing it, and no matter what do not let your life pass you by because you refused to act upon something because you really only get one chance at life so make it count.
