To treasure every moment of life means living in the present moment, Dr. Robin says. After all, the past is gone and the future is yet unknown, she says. Are you missing out on the "right now" because you're moving too fast, dwelling in the past or worrying about the future?

If you're not living in the moment, Dr. Robin says you risk letting life pass you by. Start paying attention to your thoughts, your feelings and your surroundings at this very moment because it is the only moment that is guaranteed. "This is all there is, this is all that counts," Dr. Robin says. "If I'm given the gift of tomorrow or the gift of an hour from now, then I'll make sense of that moment when it is my now moment."
