My tactic was to make the most compelling and advanced temple I could think of, so I would be able to keep it fresh in my mind without making any notes. Apart from the main building, my temple so far has several rooms representing different emotions(Ive been experimenting with emotions to fortify control and strength of my abilities, so far with much success) such as depression, blind motivation/confidence, joy/excitement, passion for knowledge, and Im about to make my latest addition of a room based on relaxation and balance/nature. Each has its own unique environment and corresponding colour according to the theme, and are all extremely expansive. I would recommend it if youre willing to put some time into it. Good luck ^^
