Pagan guidance, please! )O(

Since there are so many fellow Pagans/Wiccans here maybe y'all can answer a question for me!?

I am a solitary practioner and like it that way but recently i am struggling to find more indepth information on my Craft. I want to became an even better, more skilled and knowledgeable Witch then i already am but have hit a growth road block. I also feel strong calling to become a certified High Priestess, it comes up in Tarrot readings and dreams often along with other suttle hints the universe is giving me. But I don't know how to do this or where to take my spiritual journey from here. Guidance? Mary meet & Blessed be! )O(
