What have I been reading?
A good read for developers: How to be a Programmer: A Short, Comprehensive, and Personal Summary. Check it out here: http://samizdat.mines.edu/howto/HowToBeAProgrammer.html#id2794476.
Other books that I think every developer should read:
These books have a good deal of time tested wisdom. I refer to them every now and then. Every time I pick up these books, I begin to reflect on the way I work, and how to make it better. It reinvigorates me, and increases my productivity - I feel a renewed zeal and passion for my work - improving day-by-day. Go grab a copy, if you don't have one.
