I agree that it's better to get paid to finish a task than to spend time on a task. You have greater independence and, IMO, can provide greater value to the client. It does introduce new sources of stress, though: if you misestimate the scope or difficulty of the project, the financial burden can be sever and you have more responsibility for delivering on time. With experience, you do learn to both budget for unforeseen delays and make agreements beforehand that limit the scope of your responsibilities when, e.g., the client's spec evolves as the project goes forward.
