If you quote a number and people are happy to pay it straight up, there's a reasonable chance you're pricing too low.
You might not want to scrape out the absolute maximum each client will pay for each job (at the least, it's a very difficult thing to actually determine, and makes for a bad client experience if you're negotiating too hard), but it's always good to have a sanity check that they're not happy merely because you're charging way below market rates for your talent.
