"Just go out and DO it!" is then the wrong advice.

However "Just go out and DO!" remains good advice.

Next time you see a poster for a meetup; just go to it. Even if it doesn't sound like it'll help, just go to it.

Next time you see a request for volunteers, which you can afford the time to fulfil, just volunteer. Even if it's not something you care much about.

While you're out doing those things you'll come across people, and random events, etc. that may give you new paths to your goals.

Don't worry about achieving your goals, just do things. To use your video-game analogy: you've been looking around for things that look like they'll be useful for you. But you haven't been pressing random buttons, you haven't clicked "use" on the poster in the corner: because why would that help? But of course, sometimes there's a safe behind the poster. Or sometimes, pressing shift and K simultaneously activates the item use menu, etc.
