It sounds like you are already working hard and honing in your skills in the craft, this is good as you should always go with the natural rytham of things. We do all of us posess some psychic abilites on some level, bethis clervoyance, clear audience or clear sentinance. However being a witch by nature is someting you are born into, it's a bit like wanting to learn how to play the pianno. Some of us can manage to do it, others take to it like a fish in water and go on to play like beathoven!
However this is not to say that you cannot become a witch simply because you are not born into it, it is simply a matter of your perspective and beleif in yourself on how great or or authentic a witch you want to become. The very fact that you found yourself on this site is indicative of the fact that something spiritual inside you drew you to this place, and now that you are here you are in the best position to connect with other like minded people in the craft as well.
Magic practise can sometimes be missconstruded, you see magik itself is no different from sceicne. In itself magik is not just a science but an art, if someone where to ask me what exactly is magik, I would say "Iv'e haven't the faintest Idea", the best way to liken it to anything is planting a seed and watching it grow.
Now these are not my words, but a very special and knowageable person told me this once when I asked him the same question. So the credit goes to him on this one, since then I have studied the works of Alister Crowley and read articles on the forums here. I am by no means expeirienced in wicca at all, I am also a beginner like yourself. But rest be sured, you will find the magik that is right for you, once you understand how the craft works.
Blessed be and I wish you the very best in your endevours!
Love and Light, Eternal Seed :) x
