Tips and Ideas on a Story Plot?

I am a bit strange in my ways, but i live by them. First u need to figure out the exact place u want to end, i usually write the last few chapters first. Then put urself into that last scene where u got stuck and pretend u r the protagonist... and speak to the other characters. Its easier to think up how they will respond if u feel like u r really talking to them. U dont have to do it aloud, but try it before u call me crazy. :)
