why not both. limit yourself to 1 tutorial/book (i prefer books). then build something. For any creative hobby i think the biggest issue is not having something you want to build.
What does wonders for me is to go out into nature, a beach, a lake or a park, or even a longer train ride, with nothing but a pen and notebook, while keeping the phone in my bag. When I return usually I have a few pages of ideas.
Sometimes distraction is the main issue when it comes to having ideas.
For me it is. Even in my domain where I’m an expert and it’s fun, it only is if I’m working on something interesting.
