The way you describe things is perfectly normal to feel like that, you’re only starting out, everything feels overwhelming at the beginning and it’s so much information and it’s all so difficult, too much stuff to remember, I keep forgetting things… we all went through all of that. Blender and 3D is difficult, so what we always say is, patience, practice and grit. Be patience and as you practice you will get better without a doubt and have grit to keep persisting and coming back to practice over and over. The initial learning curve is tough, but the straight line will come, don’t you worry. Just keep at it, make all the mistakes, because that is how your brain will start to understand things, as you do it wrong over and over and then slowly start to get it right, again, that’s where patience comes in.
Keep posting your progress, we’ll help you out pointing out things where we can like Martin did.
