I'm a little bit of both! I like having very set routines so that I CAN be an adventurous person at times.
Example: I'm in the process of implementing a set of household routines so that "spring cleaning" becomes a thing of the past. This way, when a crazy mood strikes me (like the one that had me flying off to Reno a few weeks ago to see Wanda Jackson--I had to actually call a friend from junior high and tell him, "Get a room, cuz I won't be home", even though I hadn't seen him since 1987)...I can re-assimilate very quickly.
