One of the biggest tragedies we all face in this life is not death, or even losing a loved one. The biggest tragedy we face in this life is wasting the very gift of life that we have been given. It's a sad reality, but there are thousands who die each day, and many of them died with regret that they didn't do more with the life they had. This is why it is vital that we all take a long look at our lives and examine ourselves to see if we, too, are wasting our gift.
There are many reasons that people end up wasting their lives, but the main reason is that they simply took life for granted. If you want to live a full, happy, healthy, productive life, then you need to live life as if tomorrow was the last day you were ever going to see. This means that you seize every moment and squeeze every drop of the potential you can out of it. It means that you make sure that when opportunity comes to you, you don't let it pass you by, but that you reach out and take it, hungry to live life to the fullest.
