I know from experience that that’s a REALLY complicated question. To put it lightly.
First, what do you want out of game development, and by extension, your life? Deep question, but that’ll determine how you present yourself and your game.
I prefer interacting with a community and my friends by hanging out with them often. So my prefered platform is Discord (the best place to just talk to people) via the Monkanics discord. It’s a tight-knit and fun place.
But I also have supporting socials that bring more attention, like the Monkanics Godot Forum topic and my YouTube channel. But that’s besides the point.
Another good question is, what do you like doing outside of game development? Recording, editing, writing, streaming, talking, etc. You can do that on the side.
Biggest thing though it to START. Just start, ok.
You’ll figure it out as you go, but asking questions won’t get you very far.
