Just another smart fox finished reading The 12-week year by Brian Moran
Read it in the beginning of the year. I stumbled on it somehow accidentally, but, of course, being the start of the year, how not to read some quick planning/gtd/being successful book. The basic idea is simple: live in 12 weeks chunk, easier to plan, easier to implement, easier to adjust. Some good tools, as always everything after is implementation. One tool in the toolbox.
