What's small thing that always makes your day a little better?

Lately I've been realizing how much the little things can affect my mood. something as simple as a really good cup of coffee in the morning or randomly hearing a song I used to love can instantly make my day feel a bit better.

It got me thinking about how everyone probably has their own small things like that. What's something simple that always lifts your mood or makes your day a little nicer?
