For anyone who hasn't already read it, I highly recommend 'An Astronaut's Guide to Life on Earth' by Chris Hadfield. It's a highlt entertaining read with lots of anecdotes from his training and time in space. The book really gives you an appreciation for the immense levels of dedication and focus required to become an astronaut. I also think his work ethic and positive outlook on life is pretty inspirational for anyone, not just those interested in space.
