One thing that completely changed my thought process and increased intellectual faculties tremendously was working in IT, precisely in Operations. The amount of problems I had to solve helped me think in a certain way. Some problems were easy, others hard, some at leisure others under pressure, but it's the constant and consistent exercise over the years that unlocked problem solving, reason and logic capacity that I posses now and can apply in any life situation following established patterns. Logic can be described in a book, but I don't think it can be taught in a book. It's a consequence of solving a lot of problems over a long period of time. My suggestion would be to pick up any book/website with programming problems and work on them every day changing the problems every so often, however nothing beats actual work experience where you have someone to explain to you why something is a good approach and why not. Understand what is expected of you, see how it fits in the big picture and start by breaking it down into smaller pieces. It's very simple, just getting it takes time.
