How much am I worth? How much should I charge? Should I take this job?
These are the kinds of questions any thinking person asks themselves from time to time. If your work is such that you’re constantly trying to secure new clients on an ongoing or freelance basis, you probably ask yourself these sorts of questions more than most.
Mark Evanier has a great post about all this, and in it he links to another great blog post from a guy named Tom Richmond whose work you may have seen in MAD. Go read them both. There’s nothing of value I could add, no matter how hard I might try.
