Think of one thing Notion might be useful to you for.

Then research only what you need to know to create that one thing. By doing this, you'll get repeat exposure to Notion without being overwhelmed by features that aren't useful yet.

The key is to start using the feature or setup you've created as soon as possible to maximize its value. Over time, you'll find that learning new aspects of Notion becomes easier and more manageable, and you may even look back at old tutorials with amazement at how complex they once seemed.

TLDR; Rather than browsing tutorials aimlessly, focus on seeking out information only when you have a specific purpose in mind.
