Using Copilot to make decisions on the most important aspects of a document for example can be very effective. Instead of feeling the need to read the entire document, you can focus on getting the key insights. By asking it to summarize the document, you can save both energy and time for more critical aspects of decision making.
A prompt you could use for this:
Summarize this document
You can extend it to:
I want you to summarise this document in order for me to decide whether to proceed with its main idea or not.
