Interesting post by Whitney Hess: “What are you worth?”
What you’re worth is a question only you can answer. It’s loosely a combination of your ability, experience, and instinct. I don’t believe any of these three can be objectively measured, therefore it’s your responsibility to make a subjective assessment and assign a dollar amount to it.
Some people charge by the hour, but I won’t. If my worth requires more time to shine through, the client should not be penalized. But if my worth gets me to the answer faster, why should I be penalized?
