I use them to top up my high when I feel like a whole bowl would be too much.

The Foundation trilogy is good, but he actually linked all his Spacer books, Robot books, Empire books, and Foundation books together in an interesting way. Asimov can spin a damn good yarn and you can’t beat him for vast epic stories, but of the old-school sci-fi guys I slightly prefer Heinlein for one off stories.

I can highly recommend “The Moon is a Harsh Mistress” by Robert Heinlein. I can’t believe they never made it into a movie.
