What’s next? !!possible spoilers!!

I started playing about two days ago. I got the wasteland area, cute and green and I got a good chunk of Pokémon. I found three different gates. I haven’t gone through any of them. I have the Pokémon center built. Tangrowth is now telling me that I should go through a gate and explore other towns. If I were to leave this town right now will the only reason to come back to this first one be to make it cuter?

In the area behind the Pokémon center, in the back right corner, they have that big field with the different street lights that introduce electricity, I have no idea what to do with that so I feel like I’m gonna learn things from other places and be able to apply it to this first place. Like is this wasteland my main home? Do you all find yourselves traveling back-and-forth? I’m just worried that once I leave here I’m not gonna find any desire to come back.

Nobody tell me to just play and find out because obviously I wouldn’t be in here if I wanted to do that. I wanna play, but there is a lot to do and it’s kind of overwhelming me.
