Book reading - Life of Pi (Part 1)

I got this book as my birthday gift of last year. but I never got the chance to read through it because I was "busy".
I downloaded audio version of this book before, but I never got the chance to hear the whole because of being "busy".
I watched the movie once, amazed by the story told/directed by Ang Lee, but not sure I really understood the message.

Now I am on the edge of losing current job (true) and getting a new job (so far a wish). "Being busy" doesn't sound like an excuse any more. So, I finished reading it in 3 days.

The first impression is the same as watching the movie.

• what a great story
• but I am not sure I fully understand the messages

Maybe this novel is so rich of messages that you can get different ones from different perspectives. So to help me to sort out the messages, I will summarize the contents and touch these topic on my mind.

BTW, I am not sure it's a good book for encouragement and inspiration during job hunting. This book is more than that.
