Harry Potter and the Methods of Rationality by Eliezer Yudkowsky - introduced me to the rationalist movement
The First Immortal by James Halperin - introduced me as a sixth grader to things like cryonics, nanotech, etc. Got me thinking about a realistic ambitious nearer term future for humanity, rather than a more fantasy-like one in the other sci-fi I'd read at that point, like Asimov and Heinlein
As a Man Thinketh by James Allen - gave me much greater agency in life. Made me realize “You are today where your thoughts have brought you;
you will be tomorrow where your thoughts take you.”
