Don't worry about it. It takes the average person about 4 to 6 weeks to have their first lucid dream. I would recommend looking into ETWOLD (Exploring The World Of Lucid Dreaming, available online, in book stores, and in pdf format). It is a very good book and rather easy to read. It is basically an instruction manual, and sums up all you need to know about lucid dreaming better, faster, and more accurately than I ever could. Good luck!
