(It's kind of reminding me of an old anecdote I once heard, though, about how tough times for writers are nothing new. I gather decades ago Larry Niven said on more than one occasion that he never would have been able to write if he didn't have a big trust fund to live off of. But maybe that's a subject for another thread.)
He did? I never knew that. The secret lives of SF writers!
I know Frank Herbert did journalism work, F. Paul Wilson was a practicing physician. Leigh Bracket and Harlan Ellison did screenwriting. Some others support themselves with genre writing under different names.
The article has a point, though. OTOH, very few, I'd say almost none, of those celebrity books remain in print after the first year, unless it's a juicy, definitive autobiography, and they're usually the first books to get culled from library shelves. Has anyone seen a copy of Madonna's
English Roses lately? No?
