If that works for you to keep you in the moment - use it! I personally am not hung up on the past, I don’t get stuck in what I said or did or could have done differently - many people live so much of their lives in the past they don’t enjoy the present. For me, it’s the future. I live in the future and the future never comes. I need to realize I won, I’m a finished project, I just need to enjoy this once in a lifetime journey.
