Olaf StapledonStanding outside the science fiction "field", he wrote fictional explorations of the futures of whole species and galaxies.
I have no idea if I'm anything like Olaf Stapledon as I'm not all that familiar with his work, and have no idea what he was like as a person...
From all of Asimov's author's notes that he included in his short story anthologies, he came across as very open and likable. He had a great sense of humour (even if he bemoaned not being able to express that in his fiction) and was apparently something of a prankster.
Are you sure
you're not much like him? ;-)
