Generally, my zines are usually about the same things I find myself doodling in the margins of my sketchbooks when I'm not really thinking--animals, slice of life comics, ugly drawings of Sonic the Hedgehog. Recently though I've been writing zines about more personal things, like multi-ethnic identity, family and struggles with anxiety.
My favorite part about making zines is that there's no wrong answers. Literally any idea is a viable zine. It can be as simple as writing about what you did in the day to as intimate as sharing journal entries you've never shown anyone else before. There's no threshold to cross before you can share your zine. If you have an idea and you write it on a folded piece of paper, that's as valid as anything else. No one is waiting to tell you it's bad or wrong.
I think zines as a form of independent media are very important because they are empowering. The DIY attitude of zines means you can start developing an idea you want to share whenever you want, and it's not dependent on the stars aligning or uncontrollable external factors to decide how and when you can release your creation into the world. Zines let you share your voice when you want to share it, and there is no middleman trying to censor your creation. In addition, there's something beautiful about the tactile nature of zines. Your idea isn't just in your head or on a screen, it's now on paper that anyone can touch and interact with.
Zines can handle unfinished thoughts. Cultural identity is an ongoing conversation between ourselves, our families, our communities, and our countries. It's constantly shifting and evolving, and it's necessary for all of us to stay in that dialogue, even if it's confusing. Few of us are ready to write entire books about our cultural identities(yet), but that doesn't mean we don't want to talk about them or share those stories with others. In fact, sharing our own cultural stories can help us parse out the truth and our own understanding of it. For example, my new zine, "DisOriented", has been very important to me personally in understanding what it means to be third generation Chinese and how my family shed its own Chinese identity as a means of survival in America. I'm still working through it, but I want to share what I have learned so far.
