See, we Heathens don't "pray" to our Gods at all; we bid them. Whether they actually get around to it is up to them, and they don't even necessarily have dominion over the particular thing. Don't bid Woden to give you peace of mind and a quiet place to read, as such things as "peace and quiet" are probably rather foreign to Him. LOL (Heck, He's also so much of a snarky prick that He might just might grant the opposite).
There did used to be an old Shamanic practice called seithr, which involved looking into Destiny (Wyrd) and trying to alter it. The way I perceive this practice is: all things, past, present, and future, are the Weaver's Web (the Weaver being Death's Firstborn, and having the form of a spider because I'm horribly arachnophobic and yet, as an artist, simultaneously have some kinship with spiders), and this practice involves looking at that Web and altering a strand here or there, but trying not to alert the Great Spider. Some practical equivalents might be building planes to get around the fact that we can't fly, or creating media intended to push people away from a perceived trend and onto a new one.
