What is God's Will?

I'm confused and I want a good Orthodox Christain answer...

I keep reading about it, but I don't really understand that. I know it's something like what God wants you to do right? How the heck do you decipher this?

Well see alot of my Protestant friends up at college always talk about "I feel God is leading me to do..." and I feel that sometimes but I don't use it in every day conversation, well unitl now I guess. And I was just wondering how I can tell if God is leading me or not, I get little voices in my head I have since I was a kid, some of them telling me to do bad things (to which I usually reply "get behind me Satan" in my head), some of them telling me to do good things which I'll be honest I don't always obey, and telling me to do things which don't seem to matter like "walk on the right side of that sidewalk" or "go around the long way." I remeber praying as a kid that I could hear God. I've heard monks talk about this, but God would not tell me to do anything bad so I know those aren't Him. I also heard a priest-monk say once that if he prayed really late into the night there was a small voice and that it was God speaking to him. Well you probably all think I'm nuts now so reply away....thanks...and if we could get some clergy in on this that too would be a plus!

Oh yeah one more thing I almost forgot...I also read recently in an artical on prayer in the OCF Basial Leaf that your supposed to ignore such voices during prayer, yeah so I'm confused...
