(FORTUNE Magazine) – Disney CEO Michael Eisner is finishing a new book about how he learned leadership and drive ... at summer camp. The book, aptly titled Camp, from Warner Books (which like FORTUNE is owned by Time Warner), won't be in stores until next June. But paging through Eisner's 1998 autobiography, Work in Progress, in which he mentions Keewaydin, his beloved all-boys Vermont camp, seven times, we pieced together a few themes the new book may address.

ALWAYS PLAY OFFENSE When Eisner was 7, his father volunteered him for a camp boxing match against a 9-year-old twice his size. He survived.

YOU'RE NEVER TOO YOUNG TO NETWORK Other famous Keewaydin alums include Senator John D. Rockefeller IV and Pulitzer Prize-winning author John McPhee.

LEARN FROM YOUR PREDECESSORS' MISTAKES Eisner's dad was thrown out of camp at 17 after being found with a girl in a canoe after-hours.

Eisner credits Keewaydin for teaching him to be "a good winner but an even better loser." These days, that's a lesson plenty of CEOs are learning the hard way. --Julie Schlosser
