I started learning about Wicca and Wiccans when I entered University. But it was kinda hard because there wasn't a coven where I could join. Being Wiccan or a witch is a lonely road. I got somewhere but, again, it was hard.
I cut short my learning of Wicca. However, I still keep in mind the Wiccan Rede or tennent: "An it harm none, do what thou wilt." It basically means that you can do what you want as long as nothing and no one, even yourself, gets hurt. That's one of the principles I use in my daily life.
