I'm answering Steelmagghia's Question!
You should put posters that have inspiring quotes of famous physicists on the walls. For example, Einstein once said something along the lines of, 'if a cluttered desk indicates a cluttered mind, what does an empty desk represent?'. Actually, that's probably not that great an example but I'm sure there are plenty of great quotes you could use. You could design the posters yourself, for a personal touch.
