Late to the party. How does one go about worldbuilding?

Here's my story:<br>I've been building worlds for over two decades. I have a hard time distinguishing reality, and fantasy. I used to be a Dungeons and Dragons dungeon master. Some of my campaigns went on for over a decade. In my most recent campaign I built a world so intricate it was hard to keep up with. The players could have easily taken a left turn at a fork in the road, or asked a single question, and the entire campaign could have changed. I like to think I'm not a very good storyteller, that I'm much better at creative problem solving.<br>I didn't have an imagination as a child, but as an adult it seems I've developed one. Recently I've been trying to learn to create digital art. I didn't have any experience with art before, so it's been a long journey. One day I decided I wanted to make a map. I lacked experience with digital painting so I drew line art with a mouse instead of painting a map. As I was drawing I realized I was building a world. I didn't even know what worldbuilding was until I started reading the posts on this sub.<br>Now I'm the opposite of how I used to be. I can see myself getting so caught up in the details, the intricate things. I used to be able to throw anything together, and be happy with it. Now I spend hours researching and looking at references. I can't seem to pull myself out of the details and look at the big picture. So here's my question. I understand that the details are important, but I've taken it to an insane level. I want to know how to take a step back and zoom out. How to look at a city, and just draw it without having to know every detail about every building. I want to get to the point where I can just draw things, and let my imagination fill in the rest. I've researched many of the worldbuilding guides, and most of them just focus on the details.<br>Any advice would be nice. I've been stuck on building the same city for three months now.
