I just cannot grasp how to make a material from looking. I cant get any material to look “real”. Are there any tutorials on how to make materials or to learn about materials? Most of the tutorials are about modeling.
Maybe there is something that i dont understand. Any recommendations?
we can’t get into your head…
elaborate
best thing to do is post one of the cases where you had trouble making a material look real…
it’s difficult to help if you give abstract questions…
It really depends on what material you want to create 
In general, however, i would say that the one thing that most often gives away
a cg-material is the lack of variation. Using textures that slightly alter color and specularity,
bump maps and so on, are very important in creating good materials.
this one seems to be good enough:
