moment of frustration

I'm working on my research proposal, trying to organize my thoughts enough on paper to get approval to move forward with the research. Adhering to the George principle that the true value of the research often emerges as you conduct the research, I'm struggling to frame my study in any coherent manner. I know what I want to do, I know the main points I'm interesting in studying, but I can't get my actual questions to say what I want them to say. I always struggle with research questions, not actually asking questions but creating valid research questions with a capital R and Q. I feel like I should know what the research is going to tell me in order to write the research questions, which completely misses the point of conducting research. Maybe I'm not inquisitive enough. Maybe I'm just willing to investigate a general area and see what develops throughout the study. The latter sounds better but it doesn't help me write my proposal any faster.
