For me, getting organized has helped me by more productive. I keep my email inbox empty, and only focus on the important tasks.
The best tools I found that work for me are the Google Notebook and Remember the Milk website. I can access Google Notebook from work, home, or when I travel. I keep notes to myself which is very important to remembering important items and people's names. I also am able to keep images and website links with notes. I found this tool to be invaluable.
The other tool I like is Remember The Milk (
www.rememberthemilk.com). The name of the site is not the best, but on this site I am able to setup task reminders and organize them. Further, they have my plug-ins to other websites like iGoogle.com (use as homepage).
