Query: A fun book about growing up

Young Jones is a farmer, who hates being a farmer and can think of nothing better than to head out into space. His uncle was an astrogator, and left his books to Jones when he died. After an upheval of his home life(which he wasn't really attached to anyway) he decides it's time to head out on his own, hopefully to become an astrogator.Being young and nieve, he makes some bad calls in charachters of someone he meets on the way, and finds out the hard way that you can't trust everyone who seems nice. I'd write more, but don't want to give away the storyline. Being one of heinlein's early 'juvies' this book isn't as involved as his later and better known works, and at times I felt it was too predictable. But, Heinlein was a master of portraying people, thier dreams and desires and fears.This is a fun young adult book about growing up.
