The human mind acclimates to improvements remarkably fast, and the joy found in such novelties tends to be fleeting and quickly fade as it becomes just another normal part of everyday life we take for granted (e.g. fancy new tech, or really anything new and nice). I like to frequently reflect on how amazing it is I am alive and even exist at all!
Gratitude is truly the only effective counterdefense I've found to reduce the fade of true joys in life, like my friends and family.
