999 Reasons is a small productivity improvement application. It encourages you to focus on the one or two changes that will improve your life.
It works by offering you ten areas of interest (How to Succeed at Work, Paths to Financial Sanity, etc.). You then select one of these areas, and 999 Reasons will give you the two ways to focus your attention in that area.
Once you've mastered those two ways, you can ask 999 Reasons for two more.
NOTE: There are ONLY FOUR RESPONSES IN EACH CATEGORY - the point is you cannot improve your productivity by trying to do 999 things, you must focus on one or two.
