Society and culture does a LOT to influence ritual and such. Shamanism came form the Native Americans, tribal peoples from around the world, etc. Witchcraft rose in India and Europe. Kabbalah came from the Middle East. You get the picture. But with the advent of technology, there's new systems running around, such as Chaos Magick, and fractal-working and such.
Inner growth will influence what you work magick on, and how you do it. But the world at large creates situations for magick to be used with, and cultures vary widely.
