I, for one, recommend "Clean Code". It did not "change my life" because I was already on the path the book describes. Nonetheless it was a good validation, it certainly coalesced in a good form many topics that were simply fluctuating in my mind, and is a good reference to have around for refreshing once in a while.

To put this in context: I keep it next to "Agile Software Development" (by the same Uncle Bob), "Working Effectively with Legacy Code" (by M. Feathers), and "Refactoring" (by M. Fowler).

HTH (no, I have no direct or indirect benefit from 'advertising' these books and their authors)
