It can be as easy or complicated as you want it to be. I don't know what you want to achieve, but an easy no intrusive one I've used with success is simply making a list.
I get myself in a good mood, write a list of what I'd like, put it away and forgot about it. The quickest this has worked for me is about 3 months; that seems to be the time-line for anything I do though.
If you wanna add more to it, get the right color ink, herb, candle, paper, oil...get creative. I don't know how everyone else feels, but for me, I learned the basics, the ethics, then tailor the majick to my own style.
p.s. My friend did this and met her hubby, she did one thing I didn't, which was keep her list and edit it until she found a keeper.
