The real issue in life is, there is no rewind button. Everyday comes with its own finality. Life can only be lived forward (though its always important to reflect). The fact that life ends is what makes it so valuable. The fact that you can't go back means you have to do your best to do things right the first time around. We all make mistakes and at times we all take things for granted. However its never to late to make a course correction, that's the beauty of being human. At any point we can make a change in our lives.
