The question popped up in my mind when I got a vacation after almost 3 years and I had a chance to retrospect. In a broad sense, I have the following classification of experiences: The cherished memories, the significant events:
The times spent with the fast friends
Excursions in Nature
Books and travel
(Now) Insignificant, barely recallable events:
Visiting plush restaurants and hanging out with people who were sort of 'temporary'
Unpleasant situations at the workplace
Worrying about petty problems and outcomes
What phrases can I use to tersely describe these two sets of experiences e.g: Suppose I try to pen down what I have written above (the types of experiences): When I retrospect the past 3 decades of my life, I had two sets of experiences - |phrase for set-1, the ones that are sort of 'permanent'| and |phrase for set-2, they came as per the changes in the age but haven't lasted longer to become a memory or make a difference|.
I apologize if the question sounds vague but haven't been able to pen my thoughts precisely
