Being a witch means you practice witchcraft. It is no good saying that you are a witch if you do not practice any of that particular craft. Being a witch is not just, for me anyway, about herbal usage and being at one with nature, casting whatever form of spell/magick is necessary is a huge part of being a witch.
People tend to get their knickers in a knot about these issues and shy away from admitting they use any form of magick. But if you are a practicing witch then you are using magick. It is like a person who is a Christian claiming they are such but not actively taking part in any of that religion's activities, i.e, going to church, praying to God, celebrating the holy days and so on. A practicing witch practices her craft, or more to the point, we are active in what we believe in.
What frustrates me is when you get asked advice on something, such as "what spell can one use to help on the job front" and you hear another witch saying something like "oh, you should only do a spell after you have exhausted all other avenues first."
Basically there are certain witches who believe that one should only ever cast after every exhaustable avenue has been explored - and they mean this about every aspect of whatever you are considering casting a spell for.
Don't get me wrong, one should never use magick in place of good old common sense, and one should not cast a spell and expect everything to be handed to them on a silver platter. But, I believe casting a spell can enhance your life.
Let's take the casting of a spell for job luck.
If you don't do anything magickal then perhaps you might miss out on a great job opportunity. By casting a spell to help you find work you are opening doorways up that might not have been obvious to you had you not cast a spell. The same rules for looking for work apply, such as getting out there and searching, looking into your chosen field of expertise, or plain old sending out your CV and chasing every available job.
The spell is not going to bring a job opportunity to you if you don't put in the hard yard. You are just opening yourself up to opportunities, you are asking the universe to assist you in your search, not for a prospective employer to come knocking on your door without you even having to have lifted a finger.
The misconception that casting a spell is giving you a better advantage over others is generally what is behind the notion that you should only use magick as a last resort. Of course there are practioners who will use magick to have an unfair advantage over others, just as there are people (let's call them muggles, a la Harry Potter) in the Muggle world who would lie on their CV's, or at interviews to give themselves an unfair advantage.
In my opinion there is absolutely nothing wrong in using magick to assist you in your life, so long as you do not expect things to materialise in front of you, like some party trick, or something from an episode of Charmed, or the like. Magick is all about creating change and who is to say that by casting a spell to help you job search you won't be more open to something you would never have considered, thus an opportunity opens up and you are offered a job as admin - something you have never applied for before. This, of course, is an example and I am trying to stress the point that even if you are unqualified at something you may be offered a job with training prospects, but without the spell it may never have been opened up to you.
Using spells in your life opens up endless opportunities, and quite often all a spell has done is change the caster's perspective on something, rather than blowing the competition out of the water. All we witches need to do is apply common sense to our magickal casting and not expect the universe to hand everything to us .
