I'm rebuilding/reworking my own grimoire atm and, in poking around for inspiration here and there, I've seen a bit of a trend regarding indexes and tables of contents.

A lot of posts for Beginner Witches have looong lists of things you Absolutely Must(TM) include in your grimoire. These read almost like a super extensive syllabus that covers what seems like every topic under the sun, and are, quite frankly, completely unnecessary.

This is a friendly reminder that you don't have to include anything in your grimoire that you don't want to.

Not interested in astrology? No problem. Don't include it.

Don't work with herbs or crystals? Why spend time writing notes on them, then?

Don't celebrate Wiccan holidays? No need to include info on the Wheel of the Year.

etc etc.

Part of the reason why I never finished my last couple grimoires were the fact that I felt pressured to write extensive entries on things I wasn't interested in, or on things I already knew and thought redundant to include. I had dozens upon dozens of unfinished pages, and the knowledge that I was expected to write things on each of them filled me with such anxiety and dread that I just... stopped opening my notebook up altogether.

This time around, however, I'm taking a different approach to my grimoire. I have limited time and energy to commit to my craft, and I'd rather not spend it on shit I didn't really care about. In my new grimoire, I have not and never intend to include notes on the 'basics', or overviews of every pantheon and every deity, or summaries of the different types of witches or spells or what have you. I'm including only what I think is important to me.

Your grimoire is supposed to be your personal journal, documenting not only the things you've learned but the things you're actually interested in. That doesn't mean you shouldn't do research -- it's very important to expand your education, especially regarding different worldviews and outlooks to your own. But!!
