Get a journal started. Write and take notes, preferably digital notes. Get your head clear on what you’re trying to do. Maybe there are people out there who can execute a big undertaking by just bumbling forward on the thought/motivation of the day, but I haven’t met them.

Perhaps you’re trying to save time by asking others where to start, but I advise you to get used to making judgement calls on where you ought to put your attention.

Slow down and settle in. Work on it a little every day. Record your progress. Learn and practice.

And go easy on yourself. Everybody starts somewhere.

My first thought opening it up was "dang, that's cozy."

This feels like a viral ad

I play single player video games and I roleplay and tell stories about my characters. I’ve done it with BG3, Elden Ring, Skyrim, Oblivion, Fire Emblem, and Pokemon. I take notes and write little stories for myself. I cultivate a little headcanon universe for each game, and I even let my roleplay alter my gameplay in meaningful ways. I don’t know if anyone else plays these games like this but I haven’t found much community for it.
