If men by a razor thin margin are more inclined to doggedly pursue something to the exclusion of all else I don't understand why there aren't more men publishing romance, which absolutely requires that level of dogged pursuit. Nursing requires continued certificate renewal and continued education. It's also competitive to get into any nursing program, so much so that you indeed need a lot of dogged pursuit to get in.
