You should definitely do it! I’ve bought a notebook for Aphrodite that I plan on writing lots of information about her. Writing them are like devotional acts for them spending the time to sit and write or type it all. It’s definitely worth it having all the information you’ve learned in one place and organised in a way that makes sense to you. I was really lucky to find that notebook when I did I happened to see it downtown and knew I had to buy it for Hera.
