You read, study, learn. Then you will figure what you are being drawn to. For some, it takes a long time to choose. Others figure it out fast. There is no time in choosing. Ask yourself questions like; Do I want to include magick? Do I want to have a god or Goddess in my belief. Do I want to learn about the many gods and goddesses? Do I want to keep my beliefs and add ti it?
See, it all depends on what you believe, what if anything do you want to change. And your beliefs may change in your search, so you might start with one path, then decide another fits you better. Its all a personal preference.
May you find what you seek. Blessed Be...
