It is best we unload our regrets. They are worse than a waste of time, they keep us stuck in the past, they keep us depressed, anxious, angry, sick in mind and body. No good comes from regrets. Best to let them go and spend our time and energy being in the Now, experiencing as much joy and peace as we can in every moment of every day with every interaction we have with the people and world around us. Best to look forward with optimism rather than backward with sadness and remorse. Best we use the past to make better choices today so as to manifest a satisfying and prosperous future for ourselves and our families.
