Wiccan religion

What does it take for you to consider yourself Wiccan? Does just celebrating the holidays and respecting nature make you Wiccan, or is there more you have to include yourself in order to use that label? As far as I know (and have researched) you don't particularly need to practice witch craft for believe in any Gods or Goddesses in order to be Wiccan, but everyone of the religion thinks differently. So if there are any Wiccans here, I'd love to hear your input.
