You may not think much of it, but the NOTES application in most nokia phones is worthy of keeping as a shortcut key on your phone. You can make different notes for various lists. I came across a webpage which talked about 12 lists that will help you get things done. Here they are and you can consider opening a note file for each and keep it handy on your phone. One list I keep is a "places to go" which is useful when you are stuck for ideas and you've forgotten the restaurants that you have been meaning to go to, or you can't think of a place where you can get a good steak.
