Make every idea concrete enough to build this afternoon
Rewrite your idea with enough detail that someone could start building it this afternoon.
Andrew Ng says
A concrete idea is specified in enough detail that an engineer can go build it, unlike a vague idea like using AI to optimize healthcare assets. A concrete example would be writing software to let hospitals let patients book MR machine slots online to optimize usage. That is concrete, something you could go build this afternoon. Vague ideas get kudos because if you tell your friends you should use AI to optimize the use of healthcare assets, everyone will say that's a great idea. When you're vague, you're almost always right, but when you're concrete, you may be right or wrong, either way is fine because you find out fast.
