Trying to describe serendipity, Wikipedia says: “Serendipity is the ability of making accidental but fortuitous discoveries, especially while looking for something entirely unrelated. The word has been voted as one of the ten English words that were hardest to translate in June 2004 by a British translation company. However, due to its sociological use, the word has been imported into many other languages.”
…making discoveries, by accidents and sagacity, of things which they were not in quest of: for instance, one of them discovered that a camel blind of the right eye had traveled the same road lately, because the grass was eaten only on the left side, where it was worse than on the right—now do you understand serendipity?
I’ll try my own humble explanation of the word serendipity:
Serendipity is looking for a book you have long lost, and find an unexpected notebook you completely forgot about, and be happily surprised about it.

Serendipity is not randomness. It is unexpected relevance.
