Metaphor

Imagine that learning English is like catching butterflies with a net. At the start, your net has many holes, and although there are thousands of butterflies in the field, you don't really know how to wield your net, and only catch one or two each time. After time, you get to know the habits of the butterflies and you begin repairing your net and becoming more comfortable using it. You start catching more and more butterflies and begin noticing their subtle differences and relevance to eachother. Soon there are but a few butterflies left in the field, but your desire to possess has turned into a desire to experience. You are now content to contemplate your butterflies and watch the beauty of the landscape...

Ok, time to sleep...
