"アイデアはウサギのようなものです。いくつか手に入れて扱い方を学ぶと、たちまち一ダースになります。"

Simplified Meaning:

When you come up with a few ideas and learn how to work with them, they quickly lead to even more ideas. Think of how a pair of rabbits can soon have lots of baby rabbits. In the same way, once you start thinking creatively and develop a couple of good ideas, those ideas will multiply into many more. For example, imagine you want to start a small garden. First, you decide to plant some tomatoes and basil. As you get the hang of caring for these plants, you might start thinking about adding cucumbers, peppers, or even starting your own compost. Before you know it, your simple garden has turned into a mini-farm. This insight shows that being open to new ideas and learning how to work with them can lead to lots of creative growth. So, when you have new thoughts or plans, don't be afraid to explore them; they'll often spark even more exciting opportunities.
