You need to do way more than 3 RC's every day. Do it everytime you see anything out of the ordinary. Walk around and think about Lucid Dreaming. Have a goal you really want to achieve. Visualize yourself becoming Lucid and doing the task. Talk to people about it. Try the three major techniques and see what kind of results you get.

If you want to achieve lucidity, then you really have to make an effort, atleast in the beginning. It's all about awareness, and your intentions of becoming aware.

Good luck!
