Whatever may it be: books, food, knowledge, experiences, feelings, opinions, hardships. Just about anything. Positive human interactions, that's what I like to see in this alienated age.
I'm gonna have to give a couple of things because it's too hard to just pick one:
People being genuinely into their hobby. That just shows up on their face and makes them 1000% more interesting to just watch and listen, whether I care about that thing myself or not at all
When I find some good band that I haven't heard about before but the vibe they give off is something that reminds me of my childhood or people that I know
My plants. Whenever I see a new leaf or branch or anything, it just makes me so happy for it and makes me want to root for it
I spent a lot of time turning our garden into a pollinator paradise. Seeing hundreds of bees buzzing around the flowers gives me so much joy. I really love bees.
When I walk out of work and into the weekend. Even though my current job is good, it‘s just a feeling of freedom that I enjoy anyway. For me it is work in an office from an early time in the morning, so it‘s often also the moment I first feel sunlight on my face that day.
