Zen Habits is one of my favourite blogs. The topics covered are mostly things I am interested in, writing is great and often personal. The About-text says:
Zen Habits will cover: achieving goals, productivity, being organized, GTD, motivation, eliminating debt, saving, getting a flat stomach, eating healthy, simplifying, living frugal, parenting, happiness, and successfully implementing good habits.
