Overpopulated, unless you invented some abortion method that could remove it/them. Also if we had the capacity of fishes that lays thousands of eggs or such yeah you would have to limit things unless we discovered other planets people could live on and of.
I feel happy quite easily. Some examples from significant to silly:
The drive and accomplishment from creative expression (writing mostly, or ideas in general), observing nature, fun or aesthetic coincidences: like realizing my clothes match the carpet and bedding.
Seeing things I’ve accomplished that took a long time to do so. All of my friends both here on TBT, on Discord, and IRL plus my family make me the happiest guy in the world.

Seeing people around me flourish, even if they aren’t particularly friends of mine, makes me happy.
