Keep up the good work. There is no point in collecting everything. Delineate one's responsibilities and promulgate rejection rules by noting past decisions.
Keep notes to a minimum. Use notes to write. Rewrite notes, then erase them. Empty your notebooks as you empty your head. A documentation system must help manage waste.
Keep filing to tagging. Do organize, but only to discharge creativity. Do not shuffle around : create a piece of work.
Sitting behind your desk should be like carrying a gun, but a much bigger gun.
