I never worry about “moments ago.” However, there are a lot of “moments ago” that I would like to change, even though retrospect teaches me that lessons are learned with every passing moment.
Therefore, “moments ago” are valuable. Howzzat for armchair philosophy?
“Moments ago” are for savoring. “Moments from now” are for anticipation.
In this manner, one’s concept of “now” is expanded. Since now is actually all we ever have, it is worth the effort.
