Spreading Positivity: Saying hello to strangers. Holding doors open for people. Complimenting strangers (and actually meaning it). Doing something that will make someone laugh a little. I try to encourage people and find the best in them. I find it motivates people a lot more when you build them up for what they do right rather than breaking them down and berate them for what they did wrong.
Idk I like seeing people happy, even when I'm having a shitty day. It makes me feel like I did something productive and significant.
