In LOR terms...
It's like weaving a spell. Maybe you want to build a fireball. First, you just try to get the damn thing to show up. When it finally does, it's a rush. You do a happy dance. But just getting it to show up isn't enough. You want it to be the best fireball you can make it. And you want to conjure it in one second, not one minute.
You tweak your weave until its neat, small, sturdy and flexible. You step back and admire your work. And then you go off to kill some orcs with your new weapon. It's a warm fuzzy feeling.
