Too busy being

to bother making my office look elite. However, been at my current place for 18 months, and it is time to start making the place livable. As I mentioned, it is a corner office, so there are two walls. One wall has my diplomas and professional certifications. Each of the windowed walls have large cabinets at the base. The cabinets are about 2.5 feet tall and can also use something on them. Also, a large bookshelf runs from floor to ceiling on one of the walls. Three of the five shelves are already holding materials/files. The top two shelves are available.
I don't have any of the mid-career stuff to show off (graduated from KSU in 2008 and professional school in 2011). Already have a picture of Mrs. YB. We have no kids. More pictures could be incorporated, but I am looking to go another route. My only ideas are to incorporate some emaw paraphernalia, but I also need some contemporary professional decorations.
I am not particularly savvy when it comes to decorating, so posting pics would make my interpretation of your ideas much easier.
