I love seeing someone doing/wearing/using something and being like "whoa cool" and then copying them, that's how I've found most of my favorite things. A non-exhaustive list of things and sources includes:
• Drinking coffee out of glass mugs with milk and sugar (Jeanne Dielman)
• L'Occitane lavender hand cream (my friend Louie)
• Mini bottles of sparkling mineral water at home instead of big ones (the bad guy in the Claire Denis movie Bastards)
• Being gay (my mother)
• Jazz fusion (my father)
