Yea, I have re-read things for goals as well. I also re-read things for the mental approach it may instill for a period of time while and after reading it, to enjoy it (like you said), or to see how the perspective fits to my new mental models a few years later. Three fiction books I constantly go back to at different times are Brave New World, The Alchemist, and Prey.
I'm curious what books others go back to over time.
