Just don't call it magick lol
What I mean is that many things in magick have become of common knowledge and widely accepted. Such as mediation/yoga, no parent will be disappointed(id think) of their kid wanting to do yoga, as they know its a relaxing thing and form of exercise.
SO, all you have to rly do is to do things in a mundane manor, that is still a bit of magickal workings for u. Of course, if you truely did become obsessed with it and doing things like constantly, then maybe holding bk a bit might be wise for a while, and to focus on the simple things.
Personally I keep my magick workings to myself(well other then on here or such lol). So, that is to say, my fam don't know of my draw of notebooks, incense sticks, cup, CDs, tarot cards, satanic bible and necromonocon; or of my cupboard full of many other book, one side having books such as The Grimoire for the Apprentice Wizard, Modern Magick, books on wicca, paganism, chakras, auras, the list goes on; or the other being of novels, mostly wizardly or magickally based.
If I've learned one thing, is the word 'occult' for me deff lives up to its deffinition: secret. In this case, the secret of a part of me. Personalyl I have no prob with it, but then again it comes VERY natrual to me lol.
