Happiness can be found not only in the obvious, light flooded areas.
I smile.
A laugh.
A night sky filled with stars.
A kiss, a hug.
Dying of laughter on the floor.
Sitting back on the lake and realizing you have a good moment and asking “what is life but this moment with infinite variation?”

But happiness can also be found in pain. In the dark places that haven’t been lit and where no friend will follow.
You cry on the bathroom floor,
filling the toilet with countless tissues
until you starting risking overflowing if you ever try to flush.
But then next morning you have a song you can sing for years to come;
a poem you will read to your grandchildren and watch the smile spread wide as they think “wow, he was just as young as us once”;
a new, redefined relationship.
All these things are happiness.
