Admittedly, the titles of the last couple posts are misleading. Habits and Things aren’t in combat or anything; Neither are Getting Things Done and First Things First. I’ve just found that contrasting the different principles of Getting Things Done and 7 Habits / First Things First helps me to understand those principles better and find ways to solve my own challenges when it comes to being more productive. If you know of any other systems, principles, ideas that help you  become more productive, let me know. I'm always looking for new ideas.
