Spark or Fuel?

From the Llewellyn Tarot, the Knight of Wands; from the Beasts of Albion, the "Cow:"

          These two card draws seem very opposite to me; the characters in them are even facing opposite directions (except the calf). The Knight of Wands is full of stimulating conversation, innovative ideas and fiery enthusiasm. But he's not always your best bet to manifest those concepts into concrete designs; he's more like the match that lights the fire. The Cow, however, is the nurturer and sustainer. Creating and raising what the Knight inspired will be up to her. At times I have been in the Knight's saddle, poking others with my wand of inspiration. Yet I have friends who have fired me up about a creative project then encouraged me to run with it. I'm not sure if I'll need a saddle or a milking stool today.
