Finally
1. I learned how to move (WSAD navigation) *walk navigation
2. I learned how to edit a character *i.e. make the character (example) sit and wave instead of T-pose
3. Lights/Camera
4. Final render

I needed these four steps to be able to use the blender more times

although I don't know yet how to create the first models (example) human step by step
and although I seem to know how to apply textures to models/characters
I need some time... but since I managed to complete these 4 steps, applying textures should be just as easy

I'm changing my current opinion about blender

Now that I've managed to complete these 4 steps...
then anyone who is like me will also follow these 4 steps easily
