How can I get best utility from Apple Pencil

Bought the iPad Pro for the Pencil.

Trying to figure out how to eliminate paper. I travel a lot locally, have a lot of meetings, get a lot of documents and write a lot of notes. Don't want to carry these around in paper form. Would instead like to figure out how to use the Pencil and the iPad Pro to take notes, store them efficiently for later retrieval, and mark up documents which I also can easily retrieve from any device.

Help!
