This is the room of a very curious person.
He wants to learn all the time and therefore he hangs the important things on his walls right in front of his face.
Its really difficult not to grow in an environment thats build for making you better.
When I studied anatomy (not over yet) I hung up various pictures of anatomical representations of the skeleton and the musculature or pictures of drawings and paintings on which anatomical knowledge was used artistically.
When I did not know something (happened often), such as the name of a muscle or its location, then I just had to look up from the drawing board and had the answer right in front of me.
Again, working without obstacles is so important.
