I don't use planners, but I can see a lot of ladies (and gentlemen) loving this planner by Sunlife, in cooperation with actor Piolo Pascual, called Sunpiology. This stands out because it's a planner that encourages you to help save the environment as well as accomplish your goals every month. There's none of that pretentious crap that planners seem to promote these days (e.g "this planner will change someone's life"? O rly?)
It also features Piolo's photos from all over the world. It's all about nature, to show us what we'll lose if we aren't more careful of our environment.
