Glory
Most medical writers are in love with the language and glory of the printed word. Some even proudly wear the label "word nerd."
Your stamp, your personality, can be on every single bit of medical information—clinical studies, biostatistics—that you coax into readability. Your work is out in the world, and people read it every day, in the FDA applications for drug approval, the informational brochures that explain complex medical stuff in a few easy steps, and even blogs and articles on science-y stuff. Your glory is that your work is out there, and it will always have an audience.
