I want to reorganize my life

... but what if I can't stick to the system I pick? I am seriously in the market for a system that actually works for me. I like the 90 day planner by Pam Shaw, but I feel like it needs to be tweaked just a bit more for me. I like the idea of a control journal by Flylady, but I don't seem to keep up with it. I love the idea of a weekly file bin, but I'm pretty sure I would skip weeks and that wouldn't really be helpful. How do I get organized? I'm at a loss.
