We are all like that, and our life also seems to have a fractal dimension. In simple terms, as you look at smaller or larger pieces of life they have a rough similarity.
In nature a three foot stretch of a tidal pool's seaward edge will bare a resemblance to the view of the coastline from an airplane - and similarities persist within the views between.
Interactions between individuals, groups, and nations also have similarities. There are flirtations, unions, misunderstandings and wars. There is also an element of constant change.
This is one reason for the pursuit of wisdom, knowledge gained is frequently applicable to many fractal relationships. The multiplication of understanding engendered allows a much broader view of life.
A door that just closed has provided experience that may apply at many levels. Perhaps an opportunity now exists to apply your knowledge in larger or smaller arenas.
The trick, as someone once said, is to distill all the wisdom out of your experience you reasonably can, but no more.
