This whole "you aren't a real <x> unless you suffer through <y>" is just as unhealthy for authors as it is for programmers. Just because someone isn't grinding out leetcode on their lunchbreak or novellas on flights doesn't mean they don't have a genuine love and passion for the underlying art. Sanderson is an exceptional author, emphasis on exceptional. Most people would burn out at the pace he sets.
