I try not to label myself, but this could also be because I don't ascribe to any singular system that has an established order of titles or hierarchy. I would label myself a neophyte in magick if I had to choose a label, but couldn't be sure when I would progress from such a label as I think on the spectrum of learning and become more adept at our craft we always have a near infinite way to go.
I do have an interest in Golden Dawn, of which I still have to get myself on a path of learning of the order.
Warlock is a term I don't fully understand, as it conjures imagery of war/warrior archetypes and my intentions in magic wouldn't align with such. Wizard brings imagery of very powerful telikinetic forces of which I do not have. Shaman doesn't seem to fit either, but I do have intentions in healing through magickal practices. I do like sorcerer, but seems much too advanced for me now. Witch may work, although many will associate it with the more feminine energy, whereas I prefer something more neutral, something all encompassing without duality overlays.
I don't know if I'll ever be able to give myself a label, or fit myself neatly into one Title, I feel too eclectic in my leanings to comprehend it at this stage. Because I have interest in Qabalah, I'm wondering if Qabalist would be fitting once I have more knowledge and abilities in this area.
Thanks for bringing this up as I'd be interested to hear what others have to say on this subject as well.
