I'm feeling down. Reddit, cheer me up and tell me something you've done to genuinely improve life on this planet

I'll start: I worked as a nurse's aide at an Alzheimer's & dementia facility and I gave caring for the residents my all. I would try to spend time with them and make them laugh... cheer them up when they think they have lost their toddlers (mean age = 80)... make sure they were clean and comfortable. Even if they forgot that I made them happy, I still feel good about it.

What about you?
