I treasure my copy of Thinking Forth. I was at a formative age when I read it and I learnt so many great programming concepts from it. The most important being keep breaking the problem down into simpler bits so you can understand and name each bit. It is a Forth book, but I think anyone could get things out of it. Leo Brodie's cartoons are very good too. One of my favourite ones is of a machine called the "Universal Processor" with a blender on top and computer keyboard underneath and a knob on the front which has three positions "Word", "Food", "Data" illustrating the danger of building over general solutions.
