When building things, steal from yourself first. Use what has proven to work, for you, when possible.
Second, steal from the conceptual information in your head. Googling things to steal is slow. Having information in your head is fast. Make the connections, and continue to learn, and build new connections, every spare minute of your life.
Third, search out something. The recommendation is to ask another human, because they have tons of information rolling around in their head. Their information together with your information, is bold.
Last resort. Invent new material for your project, only when necessary. Inventing can take a long time, and usually results is a steal anyways. Originality is in practical terms, a myth.
