Imagine people complexly.
Everyone you meet, passing in their car, or posting comments on YouTube is a person with their own interior universe, working on a model of how the world works and where they fit. Be kind. Imagine their interior universe.

Be good to yourself.
Someone will always be willing to tell you that what you're doing, saying, or creating is wrong, immoral, or inadequate. That you are fundamentally unworthy. If you listen, you'll unmake yourself piece by piece until there's nothing left. You, as you are right now, are enough.

Life is uncertain.
No one is promised tomorrow. I don't know how many Saturdays I have left or how many nights with friends I have. No one does. Eat your dessert first. Do what brings you joy. Open your mind. Acquaint yourself with your humanity. Struggle for goals that you find worthy. The time is and has only ever been now.

I say this in hopes of reaching you. Someday I will be gone, and all that will remain are these signals from beyond.
