I can relate to the casting back or past or forward part. When I was in my 20s, a friend said "J, you live in the Past Perfect." It also hurts to realize that certain situations were beautiful, I just didn't realize it at the time. I don't think that's living in the past perfect, it's expecting too much and appreciating too little.
I do better living in the present now, but I still anticipate certain events and feel disappointed when they don't live up to my expectations.
Simple appreciation of the moment is a goal of mine. Also telling those I care about that I value them. Like you, Pink.
