…person’s treasure. There are ideas that others toss away because they don’t want to work with them. Nearly every silly idea can be useful in one of two ways: either understanding the underlying principle of it, or understanding what other ideas might be connected to it. There is fertile ground in disassembling and re-assembling ideas to cultivate new ways of thinking.
… not for what you think you can do with them.
Plenty of people pay lip service to ideas these days. Plenty of people are looking to learn about things because their job necessitates it, or because they already know what they’re going to do with the knowledge. But if you really want to have the kind of ideas that others don’t, you need to pursue new ideas for their own sake — not because there’s already a use for them. If you want to make a totally new dish, you can’t use a recipe that already exists.
