Delivering on time is good, having expectations set properly in the first place is better. Working fast can be good, solving the right problem at any speed is better. Personally I have not found my speed matters so much as my mental state. When all the things come together, I know what problem I'm solving, I know how to solve it, I have time to focus on it for many hours... That is when I can enter a state of flow and build a great head of steam productivity-wise. Finally I think continued long-term attending to something can trump speed and overcome all kinds of obstacles that prevent progress at all let alone progress at some arbitrary sense of fast.
