I agree that a lifelong commitment to learning can be a source of ongoing enjoyment. I didn't mean to imply that he should focus all of his learning activities on his job, or job related topics. What I had meant to convey was that learning was normally a component of most jobs. I also agree that taking a break from the computer and work related topics by reading a book is a great way to recharge and learn something new.
