Perhaps as important, you can notice, observe how you feel and react to the things in the present. When I was a kid I wanted a Fanner Fifty two gun cap pistol set in the worst way. Santa brought me one and in short order I noticed how much cheaper and tinny they looked in my hands than they did on TV. On the other hand I still have the hard bound Sherlock Holmes anthology my Aunt and Uncle gave me that Christmas…60 years later and read many times;) Good to feel your feelings, including the bad ones, good to observe how they arise and what ways of dealing with them seem to succeed.
