tarot card theme ideas?

I've been really good at tarot cards since I first tried them (I know that theres always the possibility that I could be reading too deeply into something but just trust me here, the answers I got were way to specific to something I was going through at the time for me to not be at least a bit weirded out) and now I want to try to design my own. It will take a really long time but it sounds really fun.

Only problem is I dont really know what the designs would be. Any ideas or suggestions that could kick start it or inspire me?
