Desk and paper question

I’m nervous and excited about desk organization this week. I do not like my area of the office and I’m ready to make a change. Part of the “problem” is that I have so much paper that’s just laying by my desk and it drives me crazy! I’m wondering if you would recommend going through all of our paper like we are everything else. The reason I haven’t done this yet is because I’m not as savvy on what to keep and what to get rid of. And also because my back starts hurting after 15 minutes of going though paper! After writing this post out now I’m realizing that I just listed obstacles and now I can go create strategies to get this done 😆. Anywho, if you have any thoughts to shed I’d still appreciate them!
