I try to make it a habit of paying attention to people's interests and preferences - their favorite drinks, snacks, books, movies, or colors - and surprise them every now and then with small gifts or recommendations tailored to their tastes. It doesn't take much time, but it shows that you care.
Also, a fun way I've been trying to spread kindness recently is by leaving sticky notes for strangers with a compliment or a simple 'You Rock!' Sometimes, seeing a unexpected positive message can make someone's day, and it only takes a minute to write.
I love hearing about these little hacks - they're so uplifting!
