One has better chances of success in magical work by actively enforcing the spell on a physical level. I've learned this early on from people like Scott who know what they're doing and are very good at it. If you cast for a job, you also apply your resume to more than a few offers, show up at interviews and do your best. If you cast for love, you expose yourself to the world more often, mingle, socialize and do your best. And so on.
But this article deals with the follow-up work from another perspective. I've noticed more than once that spells aimed at a person to create microcosmic changes, such as physical or psychological healing, often impose the need for the person to conduct certain works for and on themselves. Although I'm not coming up with any theory, the probability for such an occurrence ought not to be overlooked by people who cast on both their and others' microcosm.
Failure to do so can generate tensions in the individual on whom the spell was cast. This can cause more unpleasant outcomes later on and what could have been a successful spell goes bust. Again, I'm not coming up with any theory as this needs further study and experimenting, but the so called blockages a person is sometimes said to put up against a spell that would benefit them can be explained thusly.
