I tend to alternate between two extremes.  One extreme is "get shit done anyway you know how ASAP!"  The other is "learn, explore, take your time, and do things right."  I let my own ambitions determine which zone I'm in, and they last from a couple weeks to months.  What I learn while I'm in the "take it slow" zone always helps me be more productive in the "do it now" zone.  And the do it now zone helps keep me motivated to learn more stuff, and the cycle repeats :)
