Question: How do you make up your mind on a tattoo?

I really want one but finding a concept I like is like pulling teeth. I want something original but I like stuff that's pretty common. The first idea that really hit my heart was a hannya split in half with flowers inside but then I saw so many other images with that design it just didnt feel original anymore. I really liked the meaning I thought of for it: Hannya = deep sorrow and rage and flowers = beauty. I struggled with mental illness so that's the sorrow and rage but the flowers are the beauty within (it inspired me, taught me to look at the world in a different way, ect) Maybe the truly original tattoo doesnt exist? Idk
