Appreciation

Why is it that it takes one to pass away for others to realize the point where they need to, "cherish what they got, and others around you before they're gone?" I think this should be an everyday type of thing. It should be something that everyone feels everyday. For someone to appreciate what they have, what they've got, and what is yet to come. You should already feel like your cherishing every moment like its the last. You should already acknowledge the people around you and never forget why they're there. But why does it take one to pass away to realize that this is a "wake up call"? I mean yes, sometimes we're so busy with life that we hardly even take the time out to realize how much we have in our lives that we never really appreciate it for being there, or never seen how great life really is, and when reality hits, and that someone you love or someone close to you has passed away or has gone,walked out of your life, that's when you start being real, start to realize that you should be thankful for what you already got and you should of appreciated what you had before it was too late. Don't sit there and say, "you don't know what you've got till its gone." Its more like you know what you got, you just don't realize how important they we're until they're gone...you know? I don't know its something to think about I guess.
