Other ways to make your freelancing life easier:

Taking the to-do list online. Which sounds a lot to me like procrastination, but to each his own.

Copyright stuff is boring and dull but you should know how it works anyway. From the Stanford University Libraries.

Working on a children's book? Yeah, you and everyone else. There is an association for you.

Not completely infallible, but some good information for free at the Writing for Dollars (Eck. sorry, that sounds like "Pennies for Babies" or something like that) Guidelines site.
