To be able to look back upon one's life in satisfaction, is to live twice.
It is a time of satisfaction and fulfillment. You should count your blessings, appreciate what you have, and bask in your current good fortune. Overall, contentment is the theme.
You may be feeling that you're missing something deep down. You could be disappointed that your wishes are not coming to fruition. You may be indulging yourself. It is important to work on your empathy and consider how your actions and words may impact others.
