While I find the smell of earth after a drizzle really comforting after a rough day, something I find on par is the smell of a book.
Be it a new one, which fills me with the anticipation of a new plot, an unexpected twist or a comfy happy ending, or an old story to relive some good memories and possibly gather a new insight or point of view which had never occurred.
Also the scent of a baby, kind of a sweet scent.
That smell when you walk/drive past your favorite neighborhood bakery.
Call me crazy, but I just love how these smells drive me alive.
