Pastulio is right. Dream control comes with practice. However, time and practice don't always do it. I know, I've been LDing since I was a kid and it is only recently that I've gotten what I'd call "goddess-like" control. For me the difference was not in more time and patience, but when I read and started using the principles outlined in the thread The Nature of Dream Control by The Cusp. You can link to that thread here. It is long and on-going, but most of what you need to know to really take control in your dreams is in the first few pages.
