Any chance you can expand on what kind of life lessons you found in the Travels book? The description of the book makes it sound like it's just a collection of adventures.
The medical school part has some interesting perspective on careers/development and life goals. The world travel deals quite a bit on relationships. The inner travels part challenges a few preconceptions. I first read it about 20yrs ago and I've re-read it a few times which is unusual for me.
