Blender is difficult, I agree and symphatise
For some reason for example glass textures wouldn't work for me at all and I couldn't find the solution for hours. Now I don't remember what I did to fix it and I'm worried to work with glass ever again in case it doesn't work again xD
What works for me is trying to find tutorials specific for something I just want to create and see at the moment and treat them as a sort of base for a bigger project. I just find myself very unmotivated by the generic donut tutorials and whatnot. If something doesn't work, then I'm just kinda annoyed and don't look for the solution, since I don't really want to see the final result all that much.
The key is finding tutorials where someone explains what they are doing step by step in detail, which isn't always the easiest to find. A lot of people tend to do crazy fast tutorials, they assume you know what to click or how something works...
For example when I started out I really wanted a simple cartoon character with cartoon shading.
This tutorial was very easy to follow for the most part and taught me a lot along the way. Then I didn't quite liked the final look, so I found some other tutorial for cartoon shaders, then for a simple cartoon grass, then how to put in a sky box... Final result - I messed up a ton of things!! but I had a solid base that allowed me to experiment and I still learned a lot along the way.
I think it's good to just straight up ask other people for guidance when you are stuck with something, too
I bothered my older brother constantly since he knows 3D much better than me.
