Spider Robinson, author of the Callahan's series, Telempath, God Is An Iron, musician behind Belabouring the Obvious, and all around cool guy.

He doesn't have any that I know of specifically about reading or writing, but he does have a few that are sort of related, including one on the Ironic Overpower.

'Librarians are the secret masters of the world. They control information. Don't ever piss one off.'

"If a person who indulges in gluttony is a glutton, and a person who commits a felony is a felon, then God is an iron."

I definitely recommend to any old-school Sci-Fi fans, for people who enjoy Ben Bova and Robert Heinlein, check out Spider Robinson. ESPECIALLY if you're a fan of puns, go look at (and then read) the Callahan's series.

"What an astonishing thing a book is. It's a flat object made from a tree with flexible parts on which are imprinted lots of funny dark squiggles. But one glance at it and you're inside the mind of another person, maybe somebody dead for thousands of years. Across the millennia, an author is speaking clearly and silently inside your head, directly to you. Writing is perhaps the greatest of human inventions, binding together people who never knew each other, citizens of distant epochs. Books break the shackles of time. A book is proof that humans are capable of working magic."

Never get tired of this one. :')

"You can't build a plot out of jokes. You need tragic relief. And you need to let people know that when a lot of frightened people are running around with edged weaponry, there are deaths. Stupid deaths, usually. I'm not writing 'The A-Team' - if there's a fight going on, people will get hurt. Not letting this happen would be a betrayal."

Wise words as always.

Kill your darlings, kill your darlings, even when it breaks your egocentric little scribbler’s heart, kill your darlings.
