I have been a big fan of using Mindmapping techniques (http://en.wikipedia.org/wiki/Mind_Mapping) to plan my day, plan for my business, and plan for my personal goals, etc. This Mindmapping technique really help me organize all of the stuff in my head on paper.
But it has been tedious of writing/drawing on paper. Lately, I have started playing with this free Mindmapping software. I have played with this software and have been very addicted to it. You can download your copy from: http://freemind.sourceforge.net/wiki/index.php/Main_Page
Let me know if you have any questions. I`m not expert on it but I have been using it for about > 1 month.
