"I realised that I had probably been creating servitors my whole life and decided to benefit from doing it consciously rather than accidentally."
This one of the most important realizations an initiate can have.
"Why should you study and practice Magick? Because you can't help doing it, and you had better do it well than badly." —Aleister Crowley Magick Without Tears
"Until you make the unconscious conscious, it will direct your life and you will call it fate." --Carl Jung
This is so important to know and keep in mind that I highly recommed the following:
1. Get a magickal journal
You can get a journal at wal-mart for under 10 bucks. If you don't have one already, you're going to need one so why not go ahead and get one? :)
2. Write in the inside cover or first page "Magick is doing consciously what I have done acidentially." Or something like that in your own words.
With that said: any time you focus intentionally on anything for an extended period of time you use up your "willpower energy". When you start to run out, you begin to feel tired. It's like a muscle, so the more you exhaust it the more you get. The phenomena of being tired (and needing to recharge) is well known in psychology as ego depletion.
