Paul Grahm: “The Ideas for Startups”を読んで気になった部分にコメントしようと思いましたが、眠いので今日は原文だけを紹介しておきます。

If new ideas arise like doodles, this would explain why you have to work at something for a while before you have any. It’s not just that you can’t judge ideas till you’re an expert in a field. You won’t even generate ideas, because you won’t have any habits of mind to invoke.

Of course the habits of mind you invoke on some field don’t have to be derived from working in that field. In fact, it’s often better if they’re not. You’re not just looking for good ideas, but for good new ideas, and you have a better chance of generating those if you combine stuff from distant fields.
