I’ve been warned by several spirits NOT to be overly elaborate with some pieces of work I have going on, because that places conditions on the working, each condition has a kind of “pass/fail” element, and therefore gives it a chance to feel like a failure even before it’s enacted.
I view magick as like being a cattleman in the old days, with a herd of rampaging steer, all headstrong but also not especially clever.
The direction they want to go in, is “the natural order of things” - the outcome that has the highest probability, for example the herd taking the shortest route down the valley to where there’s water and grass.
For that reason I call outcomes with no magick applied, the “probablistic outcome.”
I, as the cattleman, want to enact my single human will on this herd of different things, so I use my cowboy skillz 
and get them all moving the way i want, into the corral for example, and this is the “willed outcome.”
There’s a very low probability that the cattle would naturally move away from the valley and into the corral, this is very similar to the concept of entropy.
The purpose of magick is to screen the forces that would give the outcome with the highest probability, and which has high levels of entropy, to make events go in an unlikely direction instead - you get that awesome job you’re not really technically qualified for, your ex comes back, you win large sums at the horse race, etc.
All highly improbable, all possible, and all attainable (with lesser or higher degrees of diffculy) with magick.
Adding elaborate conditions into magick, UNLESS you have them firmly fixed in your mind NOT as hurdles to be leapt over, but absolute guarantors of success, is like not only herding the cattle into a corral, but also asking them to march in step whilst entering single file.
The odds of controlling an apparently random set of forces (or cattle) with that specific precision are very low, therefore, it’s more likely to fail altogether than if you just herd 'em up any way that gets the job done.
Hmmn, that was embarrassingly rambly (also, magicians as Kozmik Kowboys? Yeah right!) but anyway, that’s my current understanding of it.
Be very specific about the desired outcome, but as open as possible towards any route that will deliver it, which includes not making elaborate rits which may close off other possible routes for it to be delivered.
ALL JMO and ALL a work in progress. 
Yee-haw!
