Let me just point out that what I commented is a generalization and simply an excerpt of all the good practices I found during my [almost] 15 years of commercial experience.

Understanding your place in the world (namely what business value does your code bring) and worshipping communication -- even between your current self and your future self -- are what I found to be the gods I worship during my work, and it made me much more productive and valuable for my customers/employers.
