Catching the Big Fish
Desire for an idea is like bait. When you're fishing, yo0u have to have patience. You bait your hook, and then you wait. The desire is the bait that pulls those fish in - those ideas.
The beautiful things that when you catch one fish that you love, even if it's a little fish - the fragment of an idea - that fish will draw in other fish, and they'll hook onto it. Then you're on your way. Soon there are more and more fragments, and the whole thing emerges. But it starts with desire.
