I am currently tracking my email load, because that always seems to take up several hours each day. I have an Excel spreadsheet that I track the messages by category. It's helping me a lot to see where the mail falls and what areas I can reduce or eliminate through unsubscribing, auto-sorting, and auto-responding to.
Another area that takes up time are my daily social networking posts. These fall into the category of important and not urgent (in the sense that I can do them at any time during the day). I organize them with a laminated card system -
Laminated Cards to Organize Social NetworkingThis works *extremely* well for me. It takes maybe 2 minutes to do a given post set on all the different networks. It reaps immense rewards in terms of user interaction and traffic. The key is you do have to aim to do it daily, to keep up interest. And you want to think about how to word your post so it draws attention and conversation.
In the urgent-important category, finances are very tight for me. So I'm on a heavy push to list all the unused books, CDs, DVDs, games, etc. that I can before the holidays. People are buying right now. They won't be buying much in January. So if you have excess items to sell, now is the time to do it. It's a narrow window right now, and worth making time for.
